This paper constructs a new quality productivity indicator system is constructed from three aspects:new workers,new means of production,and new labor objects,with a total of 25 sub indicators.The AHP-Entropy Method-Game Theory combined weighting method was used to measure the development level of new quality productivity in 30 provinces(regions,municipali-ties)of China from 2010 to 2022.The Kernel density estimation,Dagum Gini coefficient and decomposition method,Moran's I index,and convergence models were utilized to analyze the evolution patterns and convergence of new quality productivity in China and its three major regions.The research results indicate that the level of new quality productivity in China continues to rise in all regions,especially in the eastern region,which surpasses the national average and the central and western regions.However,in terms of regional differences,the disparity in new quality productivity is widening,primarily due to inter-regional differences.In terms of spatial evolution,there is a significant positive spatial correlation and spatial agglomeration characteristics in the new quality productivity of each region,but the agglomeration effect is weakening year by year.Regarding convergence,there is no apparent σ convergence in new quality productivity at the national and regional levels,but there is β convergence,with the western region exhibiting the fastest convergence rate.

In the context of population aging,the development of new quality productivity is the inevitable choice to achieve the high-quality development of the manufacturing industry,and accelerating the formation of new quality productivity is the inhere-nt requirement of the high-quality development of the manufacturing industry.In order to explore the relationship between populati-on aging,new quality productivity and high-quality development of manufacturing industry,this paper uses the entropy weight method to establish the index system of new quality productivity and high-quality development of manufacturing industry,and empirically analyzes the relationship between population aging,new quality productivity and high-quality development of manufacturi-ng industry by establishing a spatial Durbin model.The empirical results show that population aging has a significant negative im-pact on the high-quality development of the manufacturing industry,and the level of new productivity has a significant positive impact on the high-quality development of the manufacturing industry;the high-quality development level of the manufacturing industry is improving year by year,and there is still a large gap between the high-quality development level of the manufacturing industry in the eastern coastal region and the central and western regions,showing the characteristics of unbalanced development;the high-quality development level of the manufacturing industry in different provinces has a certain spatial correlation;the negative impact of population aging on the high-quality development of the manufacturing industry in the eastern region is the most significant,and the negative impact on the central and western regions is small,showing an obvious unbalanced effect.

The development of new quality productivity and the enhancement of regional economic resilience are important ways to promote the high-quality development of the regional economy and accelerate the shaping of new momentum and new advantages for development.Based on the panel data of 31 provinces,autonomous regions and cities in China from 2010 to 2022,this paper empirically examines the impact of new quality productivity on regional economic resilience and its mechanism based on the measurement of new quality productivity and regional economic resilience.It is found that new quality productivity can positively contribute to regional economic resilience.The heterogeneity results show that the promotion effect of new quality productivity on regional economic resilience is affected by the level of regional economic development and the level of urban agglomeration,and the positive promotion effect on economic resilience is stronger in less economically developed regions and regions that are not among the five largest urban agglomerations.Therefore,the development of new quality productivity should be accelerated in the light of diffe-rences in regional resource endowments to continuously enhance the resilience of regional economic development and explore differen-tiated paths for promoting high-quality regional economic development and advancing the local practice of Chinese-style modernisation.

Xi Jinping's theory of new quality productivity outlines the future trajectory of advanced productive forces and introduces new avenues for scholarly investigation.Utilizing data from A-share listed manufacturing firms from 2012 to 2023,this study develops quantitative metrics for new quality productivity and empirically explores the impact of inter-firm collaboration on its enhancement,alongside the underlying mechanisms.Findings reveal that such collaboration significantly boosts new quality produc-tivity,with an upward trend in marginal contributions.The transmission mechanism test indicates that inter-firm collaboration enhances new quality productivity through channels such as talent agglomeration effect,efficient utilization of labor tools,and joint innovation development.Further,heterogeneity analysis underscores state-owned enterprises,industry chain leaders,high digital transformation enterprises play a more significant role in promoting new quality productivity through inter-firm collaboration.These research findings enrich the theoretical literature on new quality productivity and provide theoretical support and micro-level evidence for the Chinese government's policy formulation to promote the development of new quality productivity.

Accelerating the formation and development of new quality productivity is not only a key issue of current concern in China,but also an important proposition that needs to be explored urgently.Based on the panel data of 30 provinces and cities in China,it used generalized additive model(GAM)to explore the interaction effects of innovation productivity,technology productivi-ty,resource-saving productivity,environment-friendly productivity,digital industry productivity and industrial digital productivity on the level of new quality productivity.The research showed that each factor had a non-linear positive effect on new quality productivity.Multiple factors affected new quality productivity and had a non-linear interaction,in which resource-saving productivity is the dominant factor.There were significant differences in the impact of the interaction between factors on new quality productivity,and the difference in the impact of innovation productivity,digital industry productivity combining with other factors was the most obvious.Based on this,the relevant enlightenment to promote the development of new quality productivity is put forward.The research is conducive to expanding the theoretical research on the path of improving new quality productivity and providing a reference for the government to formulate development policies.

With the transformation of economic development models and the continuous advancement of technology,new quality productivity,as an important force driving social progress,is increasingly highlighting its crucial role in achieving the goal of common prosperity.This paper begins by examining the current research on new quality productivity enabling common prosperity and its connotation and characteristics.Through an in-depth analysis of the theoretical logic behind how new quality productivity promotes common prosperity,the paper further proposes the theoretical logic and practical pathways to facilitate common prosperity.

This study takes 107 resource-based cities in China as the research sample,uses two-way fixed effects model to empirically analyze the impact of digital economy development on the industrial homogeneity of resource-based cities from2012 to 2022,and identifies the internal mechanism.The results show that:(1)the development of digital economy can significantly al-leviate the industrial homogeneity of resource-based cities,and the reliability of this conclusion is verified through a series of robustness tests.(2)The influence of digital economy development on the industrial homogeneity of resource-based cities has significant heterogeneity.Among which,the development of digital economy can significantly alleviate the industrial homogeneity of growth and maturity resource-based cities,resource-based cities in central and western China and small-sized resource-based ci-ties.However,the development of digital economy has no significant impact on the industrial homogeneity of recession and regeneration resource-based cities,resource-based cities in eastern China and large and medium-sized resource-based cities.(3)The development of digital economy can alleviate the industrial homogeneity of resource-based cities by promoting green innovation and the industrial structural rationalization.The conclusions of this study provide guidance for alleviating the industrial homogeneity of resource-based cities and realizing their industrial structure transformation.

Digital infrastructure is an important engine for promoting the development of unified national market and achieving high-quality economic development.This paper demonstrates the role mechanism of digital infrastructure in promoting the construction of unified national market from the perspective of industrial chain coordination between cities.The results show that digital infrastructure can promote the construction of unified national market and have positive spatial spillover effect on the unified large market of surrounding cities.Mechanism inspection finds that digital infrastructure promotes the construction of unified national large market by enhancing the matching of supply and demand information between cities,deepening the division of industrial chain labor and the sharing mechanism of industrial chain elements.Further studies revealed that the geographic threshold for spatial spillover of the digital infrastructure is approximately 300km.The spatial spillover effect of digital infrastructure in the eastern region on the national unified large market in central and western China,and the digital infrastructure in big cities has significant positive spatial spillover effect on the national unified large market of small and medium-sized cities.Therefore,this paper proposes that the digital transformation policy should be implemented according to the city,and the design of the coordination of industrial chain between cities.

Innovation is the key to maintaining the vitality and vigorous growth momentum of China's economy in the new stage of development,and the institutional reform represented by the policy of cross-border e-commerce comprehensive pilot zone is a magic weapon to promote innovation since China's reform and opening up.Based on the patent application data of listed companies from 2011 to 2020,this article uses the multi-time DID method to investigate the impact of cross-border e-commerce comprehensive pilot zone(CBEC pilot zone)on enterprise innovation.It is found that the market price competition caused by trade facilitation and the innovation crowding-out effect caused by technology dependency in CBEC pilot zone have significant negative impacts on enterprise innovation,and have a more obvious effect on strategic innovation and the innovation of state-owned enterprises tertiary industry enterprises,large-scale enterprises and those in the eastern region of China.To this end,this article puts forward policy propositions such as strengthening policy coordination and attaching importance to innovation protection.

Digital trade rules serve as a crucial impetus in propelling the exportation of Information and Communications Technology(ICT)products among nations participating in the"Belt and Road Initiative"(BRI).Existing research primarily focuses on digital trade rules led by developed countries and their trade effects,while overlooking the digital trade development of emerging and developing countries participating in the BRI.This paper focuses on the countries co-building the BRI and delves into the impact of digital trade rules on the export of products.Utilizing bilateral data from 123 countries between 2000 and 2023,combined with social network analysis,we reveal the changes in the network structure of digital trade rules and construct indicators to measure their scope and depth.After addressing endogeneity issues and conducting a series of robustness tests,the study finds that the improvement in the scope and depth of digital trade rules significantly promotes ICT product exports by reducing domestic regulatory quality differences and lowering international trade costs,thereby enhancing the digital trade environment.Heterogeneity analysis shows that,at the rule characteristic level,the effects of digitalization rules of trade modes are more significant;at the trade relationship level,signing digital trade rules is particularly beneficial for countries with distant trade relationships;at the network node structural power level,the degree centrality of contracting countries strengthens the positive effects of digital trade rules.Further research reveals that the impact of digital trade rules exhibits nonlinear characteristics.As the digital infrastructure gap between contracting countries widens,the effects follow a trajectory of"strong promotion-weak promotion-restraint".This paper enriches the theoretical research on the idea of"taking rules and standards as an important support for co-building'the Belt and Road’through soft connectivity"and provides empirical references and policy insights for developing countries on how to conduct digital trade rule negotiations and accelerate the development of ICT products.

The digital economy is an important aspect for the development of new quality productivity,which needs strong support from the science and technology financial ecology.We construct a science and technology finance ecology composed of financial input,venture capital,science and technology loan,capital market,science and technology insurance and science and technology service,and adopt fuzzy set qualitative comparative analysis(fsQCA)method to explore the configuration path of science and technology finance ecology to promote the development of digital economy in 31 provincial administrative regions in China.The findings are as follows:(1)single financial element is not a necessary condition for the development of digital economy,and the technological financial ecology plays a role through the configuration formed by multiple elements.(2)Among the two configurations in which technological financial ecology promote the development of digital economy,the performance of the government-market collaborative model is higher than that of the market-led model,indicating that the market is the basic factor for the development of digital economy,and the collaboration between the government and the market can promote the development of digital economy to a higher level.(3)In regions where high-level digital economic development has yet to be realized,underdeveloped financial markets emerge as a common problem.These conclusions offer theoretical insights and policy implications for optimizing local-specific science and technology finance ecosystems.

Building a unified domestic market is crucial for building a stable and healthy dual circulation system,and breaki-ng down inter provincial trade barriers,eliminating local protectionism,and empowering product factor circulation are important measures.This article analyzes the impact of the development level of local government digital governance on the business environment and the mechanism for establishing a unified large market.It constructs an indicator system to measure and evaluate the digital governance development capacity and business environment level of each province,and conducts empirical analysis through panel data models and mediation effect models.The results showed that the digital governance level of local governments can significantly improve the business environment,reduce inter provincial trade barriers,promote inter provincial flow of resource factors,and achieve rational allocation of product factors.Therefore,local governments should strengthen digital governance construction,promote government transparency,achieve cross departmental and cross provincial collaborative work,reduce entrepreneurship and trade costs,thereby lowering trade barriers,reducing resource misallocation,and promoting the construction of a unified domestic market.

ESG rating divergence,as a critical factor influencing the ESG value chain,has a vital impact on corporate value and has therefore attracted significant attention.This study uses a sample of A-share listed companies from 2013 to 2022 and employs a difference-in-differences(DID)approach to reveal the impact of supply chain digitalization on ESG rating divergence and its underlying mechanisms.The findings indicate that supply chain digitalization significantly reduces ESG rating divergence.Mecha-nism analysis shows that supply chain digitalization reduces ESG rating divergence by enhancing supply chain transparency,promoting green technology innovation,and increasing corporate disclosure willingness.Heterogeneity analysis reveals that the effect of supply chain digitalization on mitigating ESG rating divergence is more pronounced in companies with lower ESG ratings,those located in non-eastern regions,state-owned enterprises,and firms whose board members lack overseas experience.Further analysis suggests that lower ESG rating divergence can curb corporate greenwashing behavior.This study extends the existing research on supply chain digitalization and,from the perspective of digital empowerment,provides strong empirical evidence and insights for mitigating ESG rating divergence and,in turn,supporting corporate ESG development.

Since the 2008 financial crisis,China's export-oriented manufacturing enterprises have shown a trend of shifting their focus from exports to both exports and domestic sales,especially in the context of the new development pattern of dual circulation.This trend is even more evident.However,existing literature rarely focuses on the behavior of enterprises after the market turns.This article is based on the perspective of enterprise division of labor,using Chinese export-oriented manufacturing enterprises from 2009 to 2022 as samples,to empirically study the internal mechanism and boundary conditions of market turning driving the professional development of enterprises.Research has found that the market shift significantly enhances the level of specialization and division of labor in China's export-oriented manufacturing enterprises,and this conclusion still holds after considering endogeneity issues and a series of robustness tests.Mechanism analysis shows that the promotion effect of market shift on specialized division of labor for enterprises is mainly achieved by reducing the external transaction costs faced by enterprises.The impact of market shift on specialized division of labor in enterprises has significant heterogeneity,and the promotion effect is more pronounced in state-owned enterprises and larger enterprises.The market shift improves the total factor productivity and innovation quality of export-oriented manufacturing enterprises by promoting specialized division of labor.The research conclusion of this article has important reference significance for the policy-making of the dual circulation development pattern.

This article analyses the impact of new urbanisation on carbon emissions from the perspective of new urbanisation,using provincial panel data from 2008~2022,based on the double fixed-effects model and spatial econometric model,which shows that the level of new urbanisation in the country is generally on the rise,but there is a significant difference in the level of development between different provinces.Meanwhile,further research finds that there is a significant positive autocorrelation of carbon emissions in space.And the positive spatial agglomeration shows an increasing trend,and the spatial heterogeneity shows a weakening trend.Finally,it is found that the impact of new urbanisation on carbon emissions has significant direct and indirect effects,and has an inhibitory effect on local carbon emissions,while it has a promotional effect on carbon emissions in other regions.Based on the above conclusions,this paper puts forward policy recommendations such as actively promoting the development of new urbani-sation,differentiating and customising new urbanisation development programmes for different regions,and accelerating the construction of urban agglomerations led by central cities.
