The report of the 20th National Congress of the Communist Party of China once again emphasized the acceleration of the construction of New Development Pattern and focused on promoting high-quality development. To construct the New Development Pattern is a major policymaking of China based on the change of comparative advantage, a profound reform to adapt to the change of relationship of supply and demand, and a strategic plan based on the current and focused on the long-term. The key of the construction of New Development Pattern lies in the unimpeded economic circulation, but there are still some blockage points in the four links of production, distribution, circulation, and consumption of current national economy in China. To accelerate the construction of New Development Pattern with domestic circulation as the main body and domestic and international double circulation promoting each other, not only the strategic basis of expanding domestic demand should be adhered to, the strategic direction of supply side structural reform should be remained, the key blockages that restrict the economic cycle should be broken through, and a higher level of dynamic equilibrium between supply and demand should be formed, but also a new advantage for China to participate in international cooperation and competition with a high level of opening up should be created, the strategic initiative in open development should be won, and the realization of a mutually promoting domestic and international dual cycle should be promoted.

Common prosperity is an essential requirement of socialism. Exploring the development of common prosperity and regional differences in China is of great significance in promoting high-quality development. Based on the theoretical analysis of common prosperity in the new development stage, a results-based common prosperity evaluation system is built from five dimensions:affluence and prosperity, spiritual self-reliance, livable and working environment, social harmony and amity, and universal and inclusive benefit of public services. China's common prosperity is measured through the entropy weight Topsis method. Moran's I index and Kernel density estimation are used to reveal the dynamic evolution of common prosperity in seven regions, and Dagum Gini coefficient is used to analyze regional differences and sources of common prosperity. The results show that: the overall level of common prosperity in China is steadily improving; there are differences in the five dimensions of development, and the weight of livable and working environment is great, but the development of it is slow; there are gradient distribution and spatial agglomeration among regions, there is a catch-up effect in Northwest and Central China, there is a lack of development impetus in South China, and the growth rate in Northeast China is relatively low and there is a growing trend of differences compared to other regions in the future; the coordination within the region is gradually increasing, while the coordinated development between regions still has great shortcomings.

Aiming at the vehicle routing problem of the mixed fleet of electric vehicles and fuel vehicles considering both pick-up and delivery and time of use electricity tariffs, a vehicle routing optimization model for fresh food distribution has been constructed with the objective of minimizing the sum of the fixed vehicle cost, driving cost, refrigeration cost, cargo damage cost, time window cost, carbon emission cost and charging cost, and a hybrid genetic simulated annealing algorithm integrating neighborhood search is designed for solution. The results show that compared with the separation of pickup and delivery, the simultaneous pickup and delivery mode can significantly improve the distribution efficiency and vehicle loading rate; properly increasing the battery capacity of electric vehicles through technical upgrading can weaken the dependence of vehicle routing schemes on charging facilities and effectively reduce distribution costs; by comparing with the running results of the genetic algorithm and hybrid genetic algorism-variable neighborhood search algorithm, the effectiveness of the algorithm is verified. References are provided for cold chain logistics enterprises to achieve energy conservation and emission reduction, cost reduction and efficiency increase in the distribution link.

The effects of government subsidy policies are explored on the profits of each and overall supply chain members in different mixed recycling modes. The Stackelberg game model is established. The changes in the profits of each members and overall supply chain members are compared and analyzed with different recycling modes. And the numerical simulation analysis is conducted. It is pointed out that increasing the amount of government subsidy can increase the profits of each recycling entity and the overall supply chain profits in the optimal recycling mode, and the optimal recycling model for the closed-loop supply chain is obtained. The countermeasures and suggestions are proposed, such as increasing subsidy amounts, enhancing publicity and education, improving subsidy mechanisms, and building industrial clusters, etc. Theoretical basis and reference are provided for decision-making on the recycling model of the closed-loop supply chain.

In order to alleviate the pressure of increasing of pension expenditure under the aging trend, the sustainable development of urban employee pension insurance system in China is focused, and the design of pension payment standards for delayed retirement is explored. The actuarial model of pension wealth is established, the actuarial factors Φ value and α value of 9 provinces, autonomous regions and municipalities of China are estimated from perspective of actuarial neutrality, and the influence of interest rate change on actuarial neutral adjustment coefficient α value is measured. The empirical results show that delaying retirement will increase the pension wealth of participants according to current pension payment mechanism in Beijing, Hainan, Henan and Heilongjiang. If the retirement system is reformed and the retirement age is delayed, the payment standard of pension benefits enjoyed by participants at different retirement ages can be set by referring to the value of α.

To meet the increasingly personalized travel needs of tourists, customized tourism has attracted more and more attention. Aiming at the problem of tourism product customization of small group tourists, a tourism product customization method is proposed based on tourist demand and online tourism product information. Online information is used to collect tourism product information and the travel needs of a small group of tourists are obtained; according to the tourism demand, the suitable products are preliminarily selected among the collected online tourism products, the degree of the selected tourism products to meet the needs of tourists and the utility value of the tourism products are calculated, and the tourism products with the highest utility value are selected as the initial tourism products; through the further selection or adjustment, the tourism product solutions can be obtained that can meet the satisfaction of tourists up to a certain threshold. The feasibility and practicality of the method are illustrated through examples. The purpose is to introduce a customized mode of tourism products that can meet the needs of tourists.

A sound fiscal and tax system is an important guarantee for promoting high-quality development. In order to clarify the relationship between tax burden, fiscal self-sufficiency rate and high-quality economic development, and effectively implement the national strategy of integration of the Yangtze River Delta, the panel data of 41 cities in the Yangtze River Delta from 2008 to 2019 are selected to calculate the high-quality development index of the cities in the Yangtze River Delta using the extremum entropy method, and the Tobit model is used to empirically test the impact of tax burden and fiscal self-sufficiency rate on high-quality urban development. The study has found that: on the whole, the trend of high-quality development of the cities in the Yangtze River Delta fluctuates periodically, and regional heterogeneity is obvious. Shanghai ranks first, Zhejiang and Jiangsu rank second, and Anhui ranks the last. From the perspective of subsystems, the order of index of high-quality development subsystem of the cities in the Yangtze River Delta is: greenness>innovation>openness>sharing>coordination. From the empirical results, both the tax burden and fiscal self-sufficiency rate significantly promote the high-quality development, and the interaction between tax burden and fiscal self-sufficiency rate significantly promote the high-quality development, too. Among the control variables, the impact of scale of government expenditure and the level of economic development on high-quality development is uncertain, and has not passed the significance test. The industrial structure and energy consumption structure have a negative correlation with high-quality development, while the level of urbanization has a positive correlation with high-quality development.

Fiscal investment in education is a major force in the Chinese education input, which plays an important role in popularizing compulsory education and forming human capital. Human capital is the main basis of improving labor quality and realizing technological progress. It is of great theoretical and practical significance to study the functioning mechanism and regional difference of fiscal investment in education on economic growth efficiency. Under the framework of endogenous economic growth theory, the moderating effect of industrial structure upgrading is explored on the influence of fiscal investment in education on total factor productivity. According to the national data, the fiscal investment in education can directly improve the total factor productivity, the upgrading of industrial structure in the eastern and central regions of China weakens the promotion effect of fiscal investment in education on total factor productivity, while the upgrading of industrial structure in western region of China enhances the promoting effect of fiscal investment in education on total factor productivity. Among other control variables, GDP growth rate and urbanization level have a significant promoting effect on total factor productivity, but the degree of opening up, foreign direct investment, deepening finance and proportion of scientific and technological investment have large regional differences on the influences of total factor productivity. Countermeasures and suggestions are proposed accordingly.

The private economy is an important force driving the high-quality development of China′s economy. The data are used of A-share listed companies in Shanghai and Shenzhen from 2010 to 2020, the macro-level digital economy data are matched with micro-level enterprise data, and the impact of digital economy is analyzed empirically on the resilience of private enterprises from perspective of resilience. It is pointed out that the digital economy can significantly enhance the resilience of private enterprises; based on the analysis of regional, enterprise scale, and type heterogeneity, it is found that the digital economy has a greater impact on enhancing the resilience of small and high-tech private enterprises in the eastern region. And suggestions are proposed to enhance the positive impact of the digital economy on the resilience of private enterprises by implementing differentiated support policies, improving the credit enhancement system for private enterprises, and strengthening policy assistance. The aim is to provide reference and inspiration for promoting high-quality development of private enterprises.

Since the 18th National Congress of the Communist Party of China, the construction of ecological civilization has been raised to an unprecedented strategic height, and the research on energy ecological efficiency has also attracted much attention. As an important energy base and a new frontier of opening up, the Silk Road Economic Belt is of great significance to the economic development. Based on the data of the provinces along the Silk Road Economic Belt from 2006 to 2019, the Super-SBM and ML index are used to measure the energy ecological efficiency statically and dynamically, and Tobit model is used to study its influencing factors. The empirical results show that the energy ecological efficiency of the Silk Road Economic Belt has not reached an effective level and has declined in the trend; the population size, industrial structure and scientific and technological level play a positive role in promoting energy ecological efficiency; however, the structure of energy consumption and the level of opening to the outside world have played a restraining role. On this basis, suggestions are put forward to promote the optimization and upgrading of industrial structure, vigorously develop clean energy, adjust the structure of import and export commodities, and improve the innovation driven development strategy.

As an important embodiment of the regional comprehensive development ability, the business environment can fully reflect the economic development ability and comprehensive competitiveness of a region, causing widespread concern. The high-quality business environment can provide convenient external conditions for the development of enterprises, and is conducive to promoting the rapid and efficient development of local economy. In view of the current business environment evaluation problems, an evaluation system consisting of five first level indicators, namely, market environment, government environment, rule of law environment, human environment, and ecological environment, is constructed; And the method of hesitant fuzzy set distance measurement is used to build the business environment evaluation model to evaluate the business environment; Finally, four regions are taken as examples to demonstrate the feasibility and effectiveness of this method, aiming to provide an theoretical basis reference for targeted optimizing urban business environment.

Based on text calculations, the 156 new energy vehicle policies released by the government from 2012 to 2022 are quantified, the internal coordination mechanism of the new energy vehicle policy system and the internal logic of China's industrial policy development are explored through a classic model of policy coordination. The optimization strategies for the new energy vehicle policy system are proposed from a collaborative perspective. The research has found that the synergy of China's new energy vehicle policies is gradually increasing in the process of continuous adjustment, which can be divided into three stages: comprehensive development period, strategic adjustment period, and balanced development period. There are differences in policy coordination models in different periods, forming an evolutionary approach centered on infrastructure construction, planning guidance, and fiscal and tax policy coordination. The policy coordination system has evolved from coordination to balanced coordination, aiming to provide a basis and reference for the construction of future new energy vehicle policy collaborative systems.

How to promote users' contribution is the key to the development of live shopping. Based on the SOR theory, the impact model of user contribution behavior is constructed in the context of live shopping. The study finds that the quality of information, brand image, the professionalism of the anchor and the interactivity of the live broadcast have a positive impact on perceived pleasure and perceived trust; perceived pleasure and perceived trust have a positive impact on consumers' impulsive consumption and marketing information sharing; the variables of stimulation have a positive impact on consumers' impulsive consumption and marketing information sharing through perceived pleasure and perceived trust; information quality and brand image cannot directly affect impulsive consumption, and brand image directly has a positive impact on consumers' marketing information sharing; the professionalism of the anchor and the interactivity of the live broadcast cannot directly affect the sharing of marketing information, but have a negative impact on the impulsive consumption of consumers.

On the basis of reviewing the mechanism of industrial upgrading on ecological environment, using the panel data of three provinces and one municipality in the Yangtze River Delta from 2000 to 2019, a comprehensive index of ecological environment effect and a panel quantile model is constructed to explore the internal relationship between industrial upgrading and ecological environment change in the Yangtze River Delta. It is found that the industrial upgrading in the Yangtze River Delta has a significant effect on improving the level of ecological environment; the impact of industrial upgrading at different stages of environmental pollution is heterogeneous on the ecological environment; the economic growth, innovation level and institutional quality significantly promote the optimization of the ecological environment in the Yangtze River Delta, but foreign investment leads to the deterioration of the ecological environment in the Yangtze River Delta. Therefore, the targeted suggestions for the development planning of the Yangtze River Delta region are put forward, such as promoting the green transformation and upgrading of regional industries, improving the level of regional innovation, strengthening environmental governance and forcing the transformation and upgrading of regional traditional industries, etc.

In recent years, the offshore wind power projects in China have developed rapidly. Due to its high investment cost, after two years of production and operation, the post evaluation organization still needs to make statistics and analysis on the data in the process of construction and operation, so as to find the problems and improve the project income on the basis of summarizing the experience. The post evaluation of the entropy weight matter-element extension model is used to analyze the investment and construction status of offshore wind power projects from the three dimensions of project finance, construction process and technology, and the evaluation grade is analyzed by Matlab software. The results show that the financial evaluation index has the largest weight in the post evaluation index system of offshore wind power project, followed by the construction process index. Through the step by step investigation, the lower evaluation index is found out, and measures to feed back are proposed to the future investment decisions. The evaluation results of entropy weight matter-element extension model are consistent with the conclusions obtained by the comparative analysis method adopted by experts, which further verifies the feasibility and scientific nature of the evaluation model.

In recent years, the number of end-of-life vehicles has continued to rise, but the annual recovery rate of end-of-life vehicles is less than 15%, resulting in increasingly prominent problems in environmental pollution and resource reuse, etc. Based on the problem description and hypothesis, an evolutionary game model is constructed between the government and the automobile manufacturer, and the different evolutionary stability strategies of both sides are analyzed and discussed. The results show that the operating costs of both parties only affect their own decisions; the social reputation of the government has no influence on the decision-making of the automobile production enterprises, while the social reputation of the automobile production enterprises has influence on the decision-making of both parties; the probability of error reward has a greater impact on government decision-making, and the probability of error punishment has a greater impact on the decision-making of automobile manufacturers. Finally, countermeasures and suggestions are put forward for the government to encourage automobile manufacturers to take the initiative to undertake the reverse logistics of end-of-life vehicles.

With the new network media gradually occupying the dominant position in media competition, the issue of network information environment governance has gradually attracted the attention of governments. In order to prevent China from losing its dominant power in the field of network information dissemination, based on the description of the current situation of network information pollution and governance, the attribute of network information is determined by constructing a three-dimensional network information environment governance model of “Pollution-Governance-Participation (P-G-P)”, and a governance path model is proposed. The different governance paths of cyberspace information governance are verified through the case study, so as to provide basis and mechanism for cyberspace governance. To a certain extent, it is helpful to reveal the governance laws of cyberspace information, supplement and improve the existing theoretical research, and deepen the correct knowledge and understanding of government of strengthening the governance of cyberspace information environment.

As the service level has become an important factor affecting consumer choice of purchase channels, the service strategy among retailers has attracted extensive attention. In view of the simultaneous existence of positive and negative spillover effects, the game theory is used to analyze the retailer service strategy in the two cases of introducing the monitoring mechanism of manufacturers under the premise of bounded rationality of game partners. The results show that the retailer′s strategy under unconstrained conditions is only related to the income and cost of service provision, and the retailer′s behavior strategy selection under constrained conditions is closely related to the supervision, reward and punishment mechanism; Reasonable supervision, reward and punishment mechanism will greatly improve the enthusiasm of retailers. Some countermeasures and suggestions are put forward accordingly such as improving the social supervision system, optimizing the service measures to retailers, introducing reasonable supervision and rewards and punishments mechanism, so as to provide management implications for enterprise service strategy selection.

High quality development is one of the essential requirement of Chinese path to Modernization and one of the common visions of global sustainable development. In order to promote theoretical research and practical exploration of high-quality development, a systematic graph analysis and quantitative research are conducted on research literature in the field of high-quality development by using the CiteSpace tool and taking the Chinese Social Science Citation Index database as data source. The results show that the theoretical research with the theme of high-quality development is on the rise, and the number of publications is increasing year by year; economic research dominates in the field of research; the research focuses on the connotation, path, mechanism, and evaluation of high-quality development.

Under the background of gradual recovery of real estate demand in China, in-depth research on the coupling and coordination relationship between the development of real estate industry and regional economy is helpful in understanding the promoting role of real estate industry development on regional economic growth and the relationship between the two. The entropy weight method and coupling coordination degree model are adopted, the coupling and coordinated development relationship between real estate industry and regional economy are evaluated in Shenyang from 2015 to 2021. The results show that the real estate industry and regional economy in Shenyang complement each other, and the coupling degree remained above 0.9 from 2015 to 2021, indicating a high degree of coupling between the two. The overall coupling coordination degree between the two shows an increasing trend from 2016 to 2021, which is increasing from 0.586 to 0.851; the type of coupling coordination has undergone a change from intermediate coupling to primary coupling, to intermediate coupling, to good coupling, and to high-quality coupling. In addition, a comparative analysis is conducted on the degree and type of development between the two, so as to maintain good and healthy development status of the real estate industry and regional economy, and provide reference for the coordinated development of real estate industry and regional economy in other regions.

Through the systematic literature induction method, the exploratory research is done on the definition and evaluation elements of public sector value innovation. It is pointed out that compared with the value innovation of commercial enterprises, the value innovation of public sector has different service objects, different value orientation and different innovation purposes. Due to the particularity of public sector value innovation, the emphasis of its evaluation is also different. In addition to covering the representative evaluation elements of value innovation, the public interest and social effect are emphasized in the orientation of public value. Compared with the 2 dimensions of the public and public sectors, the evaluation of public sector value innovation is carried out from 4 dimensions, such as social public, public sector, social effects, public sector and multi-party public interaction. The evaluation elements include process elements and result elements, which are more comprehensive, and the evaluation system is more complete and more systematic.

Using the data of 30 provinces, autonomous regions and municipalities in the Chinese mainland except Tibet from 2009 to 2019, the relationship between population mobility, technological innovation and industrial structure upgrading is discussed by using the adjustment effect model and threshold regression method. The results show that: technological innovation has a moderating effect on the impact of population mobility on upgrading of industrial structure; the threshold model of population flow and industrial structure upgrading is tested and the single threshold effect is found; when the population flow is lower than the threshold value, reasonable population flow can promote the upgrading of industrial structure; on the contrary, the large-scale population flow has a restraining effect on the upgrading of industrial structure; in addition, in the analysis of the threshold model, the influence of regional control variables such as economic development level, education development level, urbanization level and infrastructure level on the upgrading results of industrial structure in different regions should also be considered. The research conclusion provides references for enriching the research results of influence of population mobility and technological innovation on the upgrading of industrial structure, creating advantageous conditions to attract labor, improving technological innovation ability, and promoting the optimization and upgrading of industrial structure.

The scope and frequency of Internet search for economic keywords can reflect the attention and tendency of the public, and can be used to predict economic indicators, so as to predict the economic trend. In order to solve the lag problem of the official data in the prediction of Consumer Price Index (CPI), the time series method is used to predict CPI by applying monitoring data of Internet search. Applying Baidu Index analysis method, three types of indicators are collected of macro-, micro-and investment-indicators, principal component analysis is conducted on the Baidu Index of initial indicators, and the CPI prediction model is fitted. The results show that the predicted CPI is basically consistent with the actual CPI trend, and the predicted value can be obtained one month ahead of the official data, which provides reference for grasping the macro-economic trend.

In order to study the differences of mutual assistance for the aged between China and Japan, and promote the development of mutual pension of China by understanding and learning from Japanese experience, it is necessary to make a comparative analysis between China and Japan. Based on the ecosystem theory, the ecological environment of the development of rural mutual aid pension in China and Japan are compared and analyzed from the micro-, meso-, appearance-and macro-systems. The results show that for Japan, the burden of family pension is large, the neighborhood community has formed a friendly mutual aid network, the participation of social organizations is high, and the overall pension security system is relatively perfect; for China, it has similar family pension burdens with Japan, it has certain geographical advantages than in Japan in developing mutual pension in rural areas, but there are some problems, such as insufficient participation of social organizations and imperfect security system. Therefore, in China, the sustainable development of rural mutual pension should be promoted from four aspects:improving the national pension security system, encouraging non-governmental organizations to participate in pension services, strengthening the construction of village mutual pension environment and improving the construction of “time bank” voluntary service organizations.

In recent years, the role of high-tech enterprises has been continuously strengthened in the process of economic development, but there are still some problems in Liaoning Province, such as the lack of core competitiveness of high-tech enterprises and the lack of industry leaders. The high and new technology listed enterprises in Liaoning are taken as the sample, the core competitiveness evaluation index system is constructed for the high-tech enterprises, and the data of enterprises are collected. Based on the theory of competitive advantage, the individual advantage identification model and the individual agent evaluation model are constructed and the sample is evaluated. Finally, eight industry benchmarking enterprises are identified and analyzed. Suggestions are put forward for the development of high-tech enterprises in Liaoning Province from the dimensions of resource management, R＆D capability, technical level, market adaptability and inter-enterprise cooperation, etc., so as to promote the high-quality development of high-tech enterprises in Liaoning Province.

As the product of the deep integration of financial sector and digital technology, the rapid development of digital finance will have a significant impact on the high-quality growth of regional economy. Using the two-way fixed effect model, the impact mechanism of digital finance in 31 provinces is analyzed on the regional economic development in mainland China from 2013 to 2019, and its regulatory effect is tested from the perspective of financial supervision. It is found that digital finance can significantly promote regional economic development, but there are some structural differences in the impact of coverage, use depth and digitization on regional economy. There is significant heterogeneity in the role of digital finance in promoting economic development in different regions, with the highest in the central region and the lowest in the eastern region. Through threshold effect regression, it is found that the role of digital finance in promoting the economy of central China is not a simple linear relationship, but a single threshold effect. The impact of financial regulation on regional economic development is U-shaped, and it plays an obvious U-shaped regulatory effect in the process of digital finance promoting economic development.

The data of 2016 and 2018 China family panel studies (CFPS) are selected to match households with houses, and a two-stage panel data model is constructed to empirically analyze the impact of rising house prices on household consumption from the micro-level, and discuss the wealth effect of housing assets from the perspective of heterogeneity. The results show that housing prices can significantly promote the consumption of households with houses, that is, housing prices has the wealth effect. In terms of the heterogeneity of consumption structure, the rise of housing prices significantly promotes the growth of consumption of family clothing, housing and medical care, while the impact on other types of consumption is not obvious. In terms of family heterogeneity, the wealth effect of housing is more obvious in eastern households, urban households, unmarried households, households without the elderly, and households with low and medium proportion of housing assets to total assets.

In view of the frequent occurrence of network public opinion in emergencies, a questionnaire survey method is adopted to investigate the participation of young netizens in the Internet public opinion and the extent of their being impacted on Internet public opinion. The results show that young netizens have a strong ability to identify Internet public opinion events, and Internet public opinion events have little impact on the values of young netizens; gender and education level have a significant impact on the Internet public opinion identification ability of netizens. Accordingly, some suggestions for relevant government departments are put forward such as strengthening the attention to network public opinion, innovating guidance methods, and establishing a network public opinion guidance mechanism for emergencies.

In the innovation ecosystem, all kinds of members are interrelated and interdependent. Considering the policy support of the government and the innovation service role of science and technology intermediaries, based on the interactive relationship among innovative enterprises, universities and scientific research institutes in the innovation ecosystem, the value co-creation evolutionary game model is constructed. The strategic choices are discussed of each subject in the evolution process and the stable equilibrium of the game system under the joint action, and the influencing factors are discussed about the strategy selection in the process of value co-creation by simulation. The results show that the willingness to participate in value co-creation among members restricts each other; both enterprise and university and research institute are affected by the income and distribution of cooperative innovation, the cost of choosing cooperative R＆D, the intermediary fees paid to science and technology intermediaries, and the reward and punishment of the government; the enterprise is more sensitive to innovation income, cooperation cost, intermediary cost and punishment intensity than the university and research institute. Suggestions are put forward accordingly for innovation incentive mechanism, cooperation innovation cost and policy environment.

In order to meet the heterogeneous needs of tourists for tourism products and save travel costs, the group tourism product customization services for individual tourists are becoming more and more popular with tourists. It is an important topic worthy of study how to design tourism products that meet the expectations of individual tourists as much as possible according to the differentiated needs of individual tourists so as to promote individual tourists to form a group. Aiming at the problem of group tourism product customization, a tourism product customization method is proposed considering the multi-type expectations of individual tourists. Firstly, calculated are the attribute weight of tourism products perceived by individual tourists and the difference between different value levels of tourism product attributes and individual customer expectations. And the tourism product customization scheme is then determined by establishing and solving the optimization model of tourism product customization. On this basis, the number of participants and price of tourism product customization scheme are predicted. The research shows that the lower the degree of individual expectation differentiation, the easier it is to form a group. The group competition price of tourism products is related to the number of participants and the number of people approved by each attribute. Finally, a calculation example is given to illustrate the feasibility and effectiveness of the proposed method.
