The construction of high-standard cropland can improve the quality of arable land, which is a strategic base for guaranteeing national food security. Based on the quasi-natural experiment of the high-standard cropland construction policy, the effect of high-standard cropland construction policy on the decision-making of grain cultivation on farmland was examined by adopting the continuous difference-in-differences method. The result shows that the high-standard cropland construction policy significantly increases the the proportion of grain sown area and produces a "grain-oriented" effect. The conclusion still holds after a series of robustness tests. The dynamic effect analysis reveals that as the construction of high-standard cropland continues, its effect of promoting the "grain-oriented" effect on cropland continues to increase. Heterogeneity analysis shows that the high-standard cropland construction policy is more effective in promoting the "grain-oriented" cultivated land in plain areas, higher agricultural dependent areas, and larger cultivated land areas. Mechanism analysis indicates that the high-standard cropland construction policy influences the "grain-oriented" cultivated land by land scaling, service scaling and technological progress. Further research illustrates that the development of cooperatives and agricultural credit investment can strengthen the promotion effect of the high-standard cropland construction policy on the "grain-oriented" cultivation of arable land.

Advanced scientific and technological advancements, particularly artificial intelligence (AI), are recognized as the driving force behind the emergence of new quality productive forces. The paths and mechanisms of influence between AI and productivity, however, remain unclear. A comparison between new quality productive forces and traditional productivity was first conducted, followed by an elucidation of the characteristics of new quality productive forces elements at the employee, enterprise, and industry levels, along with the application characteristics of AI. At the employee level, the “automation-enhancement" pathway was studied, along with Al's role in capability integration, learning, and reconfiguration. At the enterprise level, Al's role in enterprise functions such as marketing, innovation, and strategic decision-making is studied. Also, the structuring, restructuring, and utilization of resources are investigated. Additionally, the research delves into Al's role in shaping industry-level dynamics via the industrial, innovation, capital, and talent chains, and the mechanisms of labor substitution, spillover integration, technological innovation, and ecological synergies. Recommendations are made to support new quality productive forces development in the short, medium, and long terms. Knowledge on AI's role in new quality productive forces is expanded by the exploration, and discussion with related research is fostered.

Digital technology innovation is the technical support for the development of the digital industry and has an important impact on economic and social development in the digital era. International Patent Classification (IPC) at the level of subgroups was used to construct the quantity and quality of digital technology innovation. Based on this, the Outline of National Informatization Development Strategy issued by the Central Committee of the Communist Party of China and the State Council which is the most representative national digital industry policy was taken as the entry point. The panel data of China's listed companies from 2011 to 2020 was used to empirically test the relationship between digital industry policy and enterprise digital technology innovation. The results are as follows. The national digital industry policy has a significant effect on the quantity and quality of digital technology innovation of micro-entities. Heterogeneity test results show that the above enhancement effect is only established in private enterprises, large-scale enterprises and high-tech enterprises. The mechanism test shows that easing financing constraints, relaxing industry access and promoting enterprise digital technology investment are the three channels which national policy incentive affect digital technology innovation. It is helpful for the government to formulate reasonable policies to encourage enterprise digital technology.

Promoting digital transformation of enterprises is an inevitable requirement for achieving high-quality economic development. Command-and-control environmental regulations represented by low-carbon city pilot policies play an important role in the construction of "digital China". Based on the pilot policy of low-carbon cities as the entry point, data from China' A-share listed companies from 2007 to 2021 was used to test the impact and mechanism of command-and-control environmental regulation policies on enterprises' digital transformation by the staggered differential model. The results show that the implementation of pilot policies in low-carbon cities can effectively force enterprises to transform digitally by reducing carbon emission level, promoting green technology innovation, easing financing constraints and adjusting from directors' overseas background. The conclusion is still valid after a series of robustness tests. The heterogeneity analysis shows that the policy effect will depend on the difference of industry type and category of employment. Further analysis shows that while promoting digital transformation, the policy can also promote the expansion of enterprises and the economic development of pilot areas. The economic contribution of pilot cities is 0. 0184%. The research conclusions of this article have important implications for how the government use macro-control means to force enterprises to digital transformation and realize the coordinated development of "green" and "digital" economy.

Global contingencies and economic climate risks create uncertainty for firms. To explore the impact of uncertainty on business decisions and investment behavior of firms, economic policy uncertainty, trade policy uncertainty, geopolitical risk, and climate policy uncertainty were combined and analyzed to explore the characteristics and mechanisms of their impact on corporate investment with a sample of A-share listed companies in China from 2013 to 2022, and to further analyze the heterogeneity of the three dimensions of the type of corporate investment, the nature of the ownership system, and the type of industry. It is found that, firstly, all four types of uncertainty inhibit business investment, but the degree of inhibition varies. Secondly, economic policy uncertainty and geopolitical risk discourage business investment in fixed assets and financial assets but promote investment in R&D, while trade policy uncertainty does the opposite, and climate policy uncertainty discourages the three types of business investment. Thirdly, the impacts of trade and climate policy uncertainty on business investment are more variable than the other two. Finally, uncertainty can affect business investment through the financing constraint channel and the business external demand channel, and business growth opportunities can mitigate the relationship between uncertainty and business investment.

The "streamlining administration, delegating powers, and improving services" reform is considered a crucial measure for easing the burden on enterprises, stimulating their innovation vitality, and promoting their development. However, research on its impact on the sustained innovation of enterprises is lacking in the academic community. The impact and internal mechanisms of the "streamlining administration, delegating powers, and improving services" reform on the sustained innovation of small and medium-sized enterprises were theoretically constructed and empirically tested using 441 domestic enterprises as subjects. The results demonstrate that the "streamlining administration, delegating powers, and improving services" reform and its three dimensions-streamlining administration and delegating powers, government regulation, and public services are positively influencing the resource assembly and sustained innovation of small and medium-sized enterprises. Among these, the promotion of public services to sustained innovation is more significant, and the role of government regulation in promoting resource assembly is more pronounced. Resource assembly is found to partially mediate the relationship between the "streamlining administration, delegating powers, and improving services" reform and the sustained innovation of small and medium-sized enterprises. The mediating effect of exploratory resource assembly is more significant than that of exploitative resource assembly. Further analysis indicates that the effects of the "streamlining administration, delegating powers, and improving services" reform differ markedly among enterprises in various industries, years, and regions. Theoretical contributions and practical insights are condensed based on these findings.

Joseph Schumpeter proposed the theoretical framework of entrepreneurship and technological diffusion in his work "The Theory of Economic Development". The conjecture was put on the basis that the technology innovation driven by real entrepreneurship is bound to have deeper, broader and longer-term technological influence (diffusion), while the technology innovation driven by lower, false or no entrepreneurship can only help enterprises to obtain monopoly profits or to even manipulate research and development for additional subsidies, resulting in underperformance in technological diffusion and no further benefits for the progress and common prosperity of the society. Exposed to a broad impact from digital technologies, it provides preliminary evidence and illustrates the applicability of digital technologies in various industries to help promote model innovation (industrial digitalization). Therefore, innovations driven by genuine entrepreneurship are expected to create a wider impact, or they will contradict with the nature of digital technologies. Particularly, within the digital era, entrepreneurship has taken on new manifestations and connotations. It highlights three most fundamental core elements, especially in terms of the core values in the context of technology diffusion.

As an experimental field for deepening China's scientific and technological system reform, the organizational innovation and institutional reform of new-style R&D institutions are closely related. From the theoretical perspective of institutional entrepreneurship, the organizational innovation of new-style R&D institutions has been redefined, and a grounded theory method has been used to construct an organizational innovation process model. Research has found that new-style R&D institutions integrate and drive stakeholders externally, establish the identity of "innovation hubs", create new institutional templates internally, and construct and interpret the new identity of "innovation complexes". The two processes dynamically collaborate to jointly shape the new institutional logic that binds technology and economy. A traceable and holistic theoretical explanation for the institutional advantages of new-style R&D institutions has been presented, providing reference and inspiration for establishing and improving modern scientific research institution system and promoting the modernization of the scientific and technological innovation governance system.

As an important force driving the high-quality development of the manufacturing industry, "SRDI" (Specialized, Refinement, Differential and Innovation) small and medium-sized enterprises (SMEs) play an important role in improving the quality and safety of the manufacturing industry. "SRDI" SMEs can enhance the quality of the manufacturing industry by strengthening the innovation power of the manufacturing industry, improving the brand value, and promoting transformation and upgrading. By promoting the integrity of the manufacturing industry chain, enhancing industrial advantages and promoting the smooth flow of the industry chain, they will improve the industrial safety of the manufacturing industry. At the same time, a technology-led industrial safety guarantee mode, a market-driven industrial safety guarantee mode, a technology-led efficiency enhancement mode and a market-driven efficiency optimization mode have been formed. Based on such consideration, efforts should be made to develop "SRDI" SMEs in key niche areas, enhance their capacity, and promote their integration and development with large enterprises. For the government and relevant departments, they should strategically plan the development of "SRDI" SMEs, improve the precision of policy support, strengthen the supply of basic research technology, and improve the business environment.

Deeply cultivating the fertile ground of data elements marketization to release the value of data elements and help banks' digital transformation, which is a key initiative to make a great article of digital finance and to fully exert the financial blood supply function. Based on the panel data of 284 prefecture-level cities from 2010 to 2021, the impact of data element marketization on the banks' digital transformation was deeply explored. The results show that data elements marketization helps to promote banks' digital transformation, while this impact exhibits significant heterogeneous characteristics in terms of city capacity, financial resilience and business credit environment. Mechanism analysis reveals that resource allocation efficiency is the channel through which data elements marketization promotes banks' digital transformation, and fintech and banking competition play a positive moderating effect in the process of data elements marketization empowering banks' digital transformation. The economic consequence test finds that the facilitating effect of data elements marketization on banks' digital transformation can further act on the development of the real economy. Theoretical and practical references are provided for the implementation path of banks' digital transformation.
