This paper constructs a high-dimensional Bayesian vector autoregressive(BVAR) model and uses a factor-structured sign restriction approach to identify seven major economic shocks, including domestic demand shocks, domestic supply shocks, foreign demand shocks, foreign supply shocks, financial shocks, fiscal policy shocks, and monetary policy shocks. The paper analyzes the intrinsic characteristics, impact scope, and contributions of these shocks to China's economic cycle fluctuations. The findings are as follows: First, domestic demand and supply shocks have direct impacts on GDP and CPI, while foreign demand shocks primarily affect the Chinese economy through trade channels. The effect of foreign supply shocks on the Chinese economy is minimal, whereas fiscal and monetary policy shocks have more significant effects. Second, financial shocks, particularly real estate price shocks, have the largest impact on variables such as GDP, consumption, and investment, making them the main source of China's economic cycle fluctuations. However, domestic supply and demand shocks also make important contributions. Third, from 2010 to 2019, the moderation of China's economic cycle fluctuations is closely related to the weakening of both internal and external economic shocks. Fourth, the effects of fiscal and monetary policies on output exhibit time-varying characteristics, with both policies effectively stabilizing economic growth in response to significant negative shocks. This study provides a new perspective on understanding the complexity of China's economic cycle fluctuations and their dominant drivers, offers a novel explanation for the phenomenon of “great moderation” in China's economy, and emphasizes the importance of fiscal and monetary policies in smoothing economic volatility.

Geopolitical tensions have disrupted corporate supply chains. The U.S. collaborates with allies in reshaping supply chains to reduce reliance on China, elevating supply chain security to a national security concern. This paper investigates how geopolitical risk(GPR) affects the supply chain security of Chinese enterprises. Using Factset Revere database, we measure the security of Chinese enterprises' supply chains in 32 countries and find that firms with suppliers in higher GPR countries encounter diminished supply chain stability and resilience. GPR primarily undermines the supply chain stability within non-critical and manufacturing sectors, particularly those not in high technology. However, in terms of supply chain resilience, GPR threatens firms across all industries, regardless of strategic importance or R&D capabilities. By segmenting the sample period based on the Crimean Crisis and the Sino-US trade frictions, we find that the threats to supply chain stability and resilience from GPR have progressively emerged. This threat originates from partners' conservative shift in trading strategies and challenges for enterprises in accessing host country information under risks. Heterogeneity analysis indicates that economic nationalism, domestic political maneuvering, and regime changes in host countries amplify the disruptive effects of GPR on supply chain security, with the latter only accelerating the loss of supply chain resilience. In contrast, in high-risk countries, improving political relations, optimizing internal corporate governance, and strengthening connections with stakeholders can be strategic resources to secure corporate supply chains. This study systematically assesses the challenges Chinese supply chains face under GPR and provides insights on safeguarding corporate supply chains under prolonged geopolitical tensions.

Monetary policy uncertainty represents the implicit costs for monetary policy adjustment. With the extensive margin perspective, this study focuses on how monetary policy uncertainty affects new firm entry through the real options and financial friction channels. Using a regime-switch model with stochastic volatility to measure the monetary policy uncertainty in China and using the Chinese Industrial Enterprises Database to measure the new firm entry rate at the city-industry-year level, the empirical results show that the monetary policy uncertainty significantly inhibits the new firm entry, the result is robust to endogeneity test and robustness tests. The real option mechanism and the financial friction mechanism are effective transmission channels that monetary policy uncertainty inhibits the new firm entry. From the real options theory perspective, the inhibitory effect is more pronounced in industries with higher asset irreversibility or lower entry barriers. Further, extending the real options theory from the risk perception perspective, the results show that improvement in the macroeconomic environment weakens the inhibitory effect, and perceived uncertainty magnifies the inhibitory effect. From the financial frictions theory, the results show that the macro credit resources availability and the regional financial development mitigate the inhibitory effect. Further, using the ownership type to proxy for financial constraints, the result shows that the inhibitory effect is stronger among non-state firms. The study enriches the understanding of the extensive marginal effect of monetary policy uncertainty, and has important implications for preventing and resolving risks and optimizing monetary policy operation.

The Central Financial Work Conference in October 2023 pointed out that digital finance is one of the five major areas for the future development of the financial field. To explore the development path of digital finance and evaluate its impact, this paper focuses on the strategic cooperation between commercial banks and technology enterprises, investigating the influence of cooperation events on bank stock prices and operational performance. Results show that on the trading day when the cooperation was reached, bank stocks exhibited significantly positive excess returns, and bank performance in terms of profitability, cost efficiency, and risk management improved after the strategic cooperation. Further analysis reveals that the positive change in bank stock prices around the cooperation event was more prominent in state-owned commercial banks, as well as banks with a higher proportion of non-interest income, a lower non-performing loan ratio, a lower leverage, and a higher capital profit margin. Moreover, this effect was more significant in collaborations with large technology companies, bank-led cooperations, and relatively in-depth cooperations such as the establishment of joint laboratories. This study contributes to our understanding of how commercial banks can achieve digital transformation through cooperation with technology companies and develop digital finance through technological empowerment, providing empirical evidence and decision-making references for the exploration of digital finance development paths for commercial banks.

Financial fraud has a non-negligible negative impact on households, society and financial markets. Therefore, it is important to study the factors that influence residents to become potential victims of financial fraud. Using data from China Family Panel Studies(CFPS), this paper empirically examines the relationship between residents' financial literacy and their possibility of becoming victims of potential frauds. Results show that residents with higher levels of financial literacy were less likely to be victims of potential fraudulent projects than those with lower levels of financial literacy. Specifically, a one-standard-deviation increase in financial literacy is associated with 9.9% decrease in the probability of residents becoming victims of a potential fraudulent project, and this effect also holds in those with lower levels of assets. Further tests show that this effect is more pronounced in people who use internets. These results sheds light on the understanding of financial knowledge's role in preventing the risk of financial fraud.

Lowcarbon development has increasingly become an international consensus. Carbon border adjustment mechanism advanced by developed economies such as the European Union have, in effect, created green trade barriers that threaten China's foreign trade and industrial production. Due to differences in industrial specialization and energy structures, various regions in China can experience heterogeneous impacts, and their decarbonization costs and benefits likewise differ, requiring nuanced strategies considering both overall economic implications and regional disparities. This paper constructs a spatial structure model that integrates China's domestic carbon market, international carbon tariffs, global input-output linkages, and interregional factor mobility. It quantitatively evaluates, under unilateral and plurilateral policy scenarios, how carbon tariffs affect regional economic disparities and explores China's strategic options. This paper finds that the EU's carbon tariff imposes significantly uneven shocks across regions: northern provinces that supply energy-intensive upstream products are hardest hit, thereby widening the north-south income gap. The emergence of a climate club among major developed economies delivers a pronounced negative shock to China's trade interests. Conversely, China's participation in such a club and the acceleration of its own green lowcarbon transition can substantially mitigate overall—and particularly southeastern—income declines, even as they exacerbate economic losses in the northwest and northeast. Finally, this paper examines the effectiveness of horizontal compensation mechanisms and policies to strengthen domestic circulation, offering insights for effectively responding to shifts in global green trade rules and for jointly advancing green, lowcarbon transformation and regional coordinated development.

Forging synergistic innovation policies and continuously enhancing their effectiveness are crucial to addressing the “chokepoint” issue in core technologies. This paper evaluates the synergistic effect of basic research investment and government R&D subsidies, based on the data of regional innovation practices and the manually-sorted data on R&D subsidies and new technology investments of Chinese listed companies from 2009 to 2020. The results show that combining basic research investment with government R&D subsidies generates a significant innovation effect. By building a high-quality public-knowledge pool, basic research provides enterprises' innovation with foundational inputs, while the R&D subsidies lower the risk and cost of transforming that knowledge into commercial products. Further empirical results show that only firms with strong technology-absorption capacity can effectively identify, assimilate and integrate knowledge spillovers from the public research system, thereby aligning basic research outputs with their own R&D activities and unlocking the synergistic gains of the two policy resources. The conclusions offer significant policy implications for optimizing the allocation of innovation resources, enhancing the efficiency of science-and-technology funding, invigorating innovation actors, and achieving high-level self-reliance and self-strengthening in science and technology.

Digital technology innovation and application play a significant role in improving the information environment of an industry and driving productivity growth in related enterprises. This paper examines the impact of digital transformation among peer enterprises on total factor productivity growth and its underlying mechanisms, based on data from Chinese listed companies. The findings indicate that digital transformation among peer enterprises significantly promotes total factor productivity growth, suggesting that digital transformation exhibits horizontal spillover effects within the same industry. Mechanism testing results show that digital transformation among peer firms exerts an information spillover effect by increasing the quantity and improving the quality of information disclosure, thereby driving TFP growth. Furthermore, the higher the technological similarity between firms, the more beneficial digital transformation among peer firms is for facilitating the information spillover mechanism. Additionally, the higher the level of industry competition, the stronger the productivity spillover effect of digital transformation among peer firms. This study expands the scope of research on the spillover effects of corporate digital transformation, providing valuable insights for optimising industry information environments and refining digital transformation policies through digital technology.

This paper empirically examines the impact of intelligent applications on capital flows. The study finds that artificial intelligence(AI) has facilitated the establishment of subsidiaries by firms across diverse locations. Key mechanisms through which AI drives capital flows include reducing off-site investment management costs, expanding high-skilled employment, optimizing the skill structure of the workforce, enhancing the allocation efficiency of technological and scientific talent, and promoting the diffusion of technical knowledge. The off-site investment effect of AI is particularly significant in non-state-owned enterprises, manufacturing firms, and businesses located in regions with pronounced labor market segmentation and advanced digital infrastructure. Further analysis reveals that AI applications transcend spatial constraints, encouraging firms to invest in more distant cities. Additionally, AI applications contribute to the flow of capital from smaller to larger cities. This paper provides empirical evidence and policy insights on how intelligent transformation can facilitate the smooth flow of capital in the new era.

The separation of rural land ownership, contracting rights, and management rights constitutes a crucial aspect of China's rural land property rights system. We construct a novel general equilibrium model that includes three markets for consumer goods, land ownership, and land use rights(abbreviated after merging contracting and operating rights). It shows that after collective land enters the market, housing price decreases and reflects more on the price of the use right. We further introduce shared ownership as a financial innovation into the framework above and find that some residents who originally planned to rent or buy houses purchased shared ownership houses. Model calibration shows that allowing collective land to trade can improve the welfare of low-income rural residents and mitigate wealth inequality(the wealth Gini coefficient dropped by 16%). The further introduction of shared ownership is a Pareto improvement. This study provides essential scientific insights into the economic impacts of collective land marketization and the implementation of the shared ownership housing systems, thereby facilitating a deeper understanding of the “separation of rights” reform in rural land in China.

This paper uses data from the random classroom assignment sample of the China Education Panel Survey to examine the spillover effects of classmates' siblings' gender composition on students' outcomes. We find that a higher proportion of female siblings among classmates is associated with significant improvements in students' academic performance, cognitive skills, and non-cognitive skills. These results remain robust after accounting for potential reflection problems and omitted variable concerns. We further explore the underlying mechanisms and show that students' effort and learning attitudes serve as key mechanisms through which the gender composition of classmates' siblings generates spillover effects, with student diligence playing a particularly central role. In addition, explanatory power analyses indicate that students' effort and learning attitudes account for a substantial share of the observed effects. This study provides a new perspective for understanding the impact of gender composition on human capital accumulation.

Using the establishment of environmental courts in intermediate people's courts, we conduct staggered difference-in-differences to investigate the carbon emission reduction effect of environmental justice in China. We find that environmental justice promotes carbon emission reduction, both statistically and economically, where cities that implemented environmental courts reduced their carbon emissions intensity by an average of 6.3% and 2.079 million carbon emissions. We confirm our results are robust through an event study, heterogeneous treatment effects tests, and the instruments of Confucian culture. Channel analysis shows that environmental justice promotes the number of environmental administrative penalties and proposals of local people's congresses to be undertaken, pushes green innovation and industrial structure transformation, and improves the number of environmental petitions and proposals of local committees of political consultative conferences to be undertaken. Heterogeneity analysis finds that environmental justice contributes to the low-carbon transformation of major national strategic development regions, resource-based regions, and old industrial bases. Welfare value calculations show that environmental justice responses to climate change have some social benefits, with an average annual reduction of 14 to 97 deaths and savings of 139 to 810 million yuan in social costs.
