We develop a theory to explain that the paradoxical ineffectiveness of China's independent directors stems from a failure to achieve separation of powers. Using a game-theoretic model, we show that in dispersed ownership economies, this separation arises naturally, creating an incentive-compatible equilibrium where monitoring is effective. In contrast, China's concentrated ownership structure leads to a consolidation of powers, where the controlling shareholder acts as both principal and agent, simultaneously controlling operations, supervision, and sanctions. This power consolidation structurally neutralizes independent directors, rendering them captured monitors. This power-based framework explains two key puzzles: why governance mechanisms fail when transplanted from Type I to Type II agency environments, and why enhancing de jure board powers is futile when de facto power is not reallocated. We show that meaningful reform must reinstate power separation by externalizing the sanctioning mechanism and realigning nomination rights away from controlling shareholders.

Small and medium-sized enterprises (SMEs) are pivotal for job creation in China. This study investigates whether improving the efficiency of Value-Added Tax (VAT) rebates can promote employment in SMEs. Using firm-level data from the National Tax Survey and Chinese Customs, we find that reducing VAT rebate delays significantly increases SME employment, both on the intensive margin—by expanding employment within existing firms—and on the extensive margin—by reducing the probability of exit from export markets. Furthermore, SMEs that face greater financial constraints exhibit heightened sensitivity to VAT rebate delays. Our findings highlight the importance of streamlining VAT rebate processes, particularly for financially constrained firms, to boost employment.

While non-financial firms (NFFs) face growing vulnerabilities and enhanced interconnectedness, their systemic risk implications remain understudied compared to those of financial institutions like banks and insurers. Going beyond the existing literature, this study focuses on the systemic risk of NFFs and further reveals its effects on these firms' credit constraints. Using firm-level systemic risk data and financial data from Chinese non-financial listed firms from 2007 to 2021, we find that higher systemic risk in NFFs reduces access to bank credit, increases borrowing costs, and shortens credit maturities, thereby leading to tighter credit constraints. Systemic risk in NFFs exacerbates credit constraints through increased information asymmetry, higher probabilities of financial distress, and risk spillovers. These findings highlight the importance of systemic risk in predicting corporate financial distress and real economic weakness and its significance in banks' assessments of corporate solvency and credit risk.

While identifying the sources of carbon emissions has long been a critical focus for researchers and policymakers, there remains a notable gap in understanding micro-level drivers, particularly the relationship between digital finance and household consumption-based carbon emissions. Existing literature has paid limited attention to how digital finance influences this issue. To address this gap, this study investigates the effect of digital finance on household consumption-based carbon emissions and its underlying mechanisms, using Chinese household data. Our analysis reveals that the development of digital finance significantly increases household consumption-based carbon emissions, and this positive effect remains robust even after addressing potential endogeneity concerns. Furthermore, the impact of digital finance on household consumption-based carbon emissions is more prominent in China’s eastern region and rural areas. These findings provide valuable insights for formulating targeted carbon emission reduction policies in the context of digital financial development

According to China's newly revised Company Law (2024), companies are required to establish Communist Party of China (CPC; also, Party) organizations because Party-related activities are crucial for banks' stability. This study innovatively constructs a textual indicator to measure the development, governance, and education of the CPC organization based on annual reports. Then, we investigate the impact of Party organization construction on bankruptcy risk in 16 publicly listed banks from 2017 to 2022. Statistical analysis reveals that banks are gradually making efforts to enhance and improve internal Party organization construction. Moreover, overall Party organization construction reduces bank failure risk by inhibiting banks from engaging in high-risk business, such as interbank and shadow banking business. Compared with the Party organization construction dimensions of development and governance, the education of Party organization can better reduce bankruptcy risk. Furthermore, this reduction effect is more pronounced for state-owned banks, bigger banks, banks with profitability pressures and under financial distress, and during the pandemic period. This study expands the study of bank failure risk from the corporate governance perspective, showing that the Party organization construction contributes to safeguarding financial stability.

Leveraging the establishment of the National Healthcare Security Administration (NHSA) in China as an external policy change, we demonstrate that the government's centralized control over drug procurement platform and insurance coverage catalog significantly enhances the innovation activities of pharmaceutical companies. By manually adjusting for expenditures of passing consistency evaluation, we accurately measure effective research and development inputs. Further tests reveal two key mechanisms driving our result: first, NHSA policies negatively impact firms' financial performance and stock returns, leading affected firms to invest more in innovation; second, increased competition further incentivizes innovation, especially among firms that lose more market shares. Importantly, companies with stronger internal resources are more successful in translating these pressures into effective innovation. Our results show that the NHSA not only redefines competitive dynamics but also acts as a powerful catalyst for pharmaceutical innovation, contributing to the understanding of the policy implications of centralized public procurement.

In the context of the continuous integration and development of new-generation information technology (IT) and various industries, it is particularly important to pay attention to how the IT-affected income gap between urban and rural residents changes to affect the common wealth. This study conducts an empirical study based on 310 balanced panel data of inter-provincial China from 2012 to 2022 to investigate the specific impact mechanism of the increase in regional IT penetration on income disparity. The study finds that: 1) increased regional IT penetration widens the urban-rural and regional income gaps; 2) increased regional IT penetration widens the urban-rural and regional income gaps through the use of digital inclusive finance and deepening the digital divide, respectively. This study concludes that the government should improve the infrastructure of digital technology in rural areas as soon as possible, give full play to the inclusive and convenient role of digital inclusive finance, alleviate the digital divide between urban and rural areas, and reduce the ‘Matthew effect’, to facilitate sustainable development.

Governments are major purchasers of goods and services globally. Although previous research highlights the role of government procurement in shaping business activities, the spillover effects on peer firms' innovation efficiency remain unexplored. Through a textual analysis that distinguishes innovation procurement from general government purchases, this study investigates the effects and underlying mechanisms of government innovation procurement on the innovation efficiency of peer firms. We find that government innovation procurement significantly enhances peer firms' innovation efficiency. Our mechanism analyses reveal that government innovation procurement sends positive signals, increasing peer firms' citations of procured firms' patents, thereby improving their innovation efficiency. The heterogeneity analyses indicate that this positive relationship is more pronounced when peer firms occupy comparable market positions, operate in regions with high-speed rail, have common analysts with the procured firms, and are classified as high-tech enterprises. We also find that central government procurement, cross-regional procurement, and evaluation methods involving “competitive consultation and negotiation” significantly enhance peer firms' innovation efficiency. Overall, our findings provide theoretical guidance and practical insights for governments to foster firm innovation and advance high-quality industrial development through innovation procurement.

We investigate political budget cycles in prefecture-level cities in China by leveraging cross-province variation in the timing of the Provincial Congress of the Communist Party, which is the most significant event for promoting and reappointing prefecture leaders. Our findings reveal strong evidence of a cyclical pattern, characterized by an increase in government spending leading up to the Congress, followed by a decrease afterward. This trend is particularly pronounced for infrastructure spending, which is a crucial driver of economic growth in China. Additionally, we examine China's multi-layer government hierarchy and explore heterogeneity across prefectures. Our analysis shows that these cycles are especially evident when promotion opportunities for prefecture leaders are most prominent. In terms of revenue sources, we do not observe significant cyclical patterns for in-budget revenues; however, we do find evidence of cycles in revenues from land sales, a vital source of off-budget revenues. Our study contributes to the literature by examining both the size of government and the allocation of public funds in order to uncover distinct political budget cycles at the prefecture level in China and highlighting the vertical incentives within the multi-layer government hierarchy.

This study employs ten-wave data from the China Health and Nutrition Survey (CHNS), covering the period from 1989 to 2015. It leverages the nationwide internet speed upgrading project launched in the early 21st century as an exogenous shock. Using this variation, we construct a difference-in-differences model to identify the causal effect of broadband internet access on children’s weight outcomes. The results show that broadband internet significantly increases the probability of children being overweight. Robustness tests support these results. The heterogeneity analysis reveals that the weights of children who are older and in urban are more affected by broadband internet. Mechanism analysis reveals that broadband internet increases children’s sedentary game activities time, decreases their physical activities time, and increases their snack intake and total energy intake. This study underscores the significance of coordinated regulation of children's gaming activities by parents, schools, communities, and the government, in order to effectively reduce children's online game time, mitigate the risk of overweight, and alleviate the economic burden associated with childhood overweight.
