• 详情 Validated Corporate Narratives and Bank-Affiliated Investment: A Large-Language-Model Approach
    Technology firms are often financed on narratives about products, contracts, customers, and technological progress well before these developments appear in accounting statements. We ask when such narratives become economically informative. Our central idea is that narratives should matter more once they can be linked to later verifiable outcomes rather than treated as stand-alone text.Using listed Chinese technology firms, we develop a validated corporate narrative framework for bank-affiliated investment, a setting in which investors must screen with soft information ex ante and then monitor hard realization and downside risk ex post. We use GPT-5.1 to extract business claims from management discussion, investor-relations records, exchange Q&A, and earnings-roadshow materials, and to label later claim–evidence pairs as support, partial support, conflict, duplicate, or irrelevant. We then connect these labels to official announcements, procurement awards, permits, project updates, and negative-event disclosures to construct a validated firm-month signal. The broad merged panel contains 592 firms and 30,169 firm-month observations; the main return tests use 576 firms and 18,230 firm-month observations over 2022–2024. A simple production rule that combines a low-narrative-premium component with hard-narrative and hard-event anchors, together with a separate downside-risk gate, delivers an implementable annualized long-short return of 8.93% in bank-invested firms after trading costs. The signal is much weaker in non-bank firms, predicts future gross-margin improvement more strongly than future ROE, and improves downside screening.
  • 详情 Who Runs the Show: The Marginal Investors in China's Stock Market
    This paper identifies the marginal investors in China’s stock market and examines their impact on stock pricing. To clearly distinguish between the equity constraint channel and the debt constraint channel, we construct the capital ratio factor and the debt constraint factor for banks and securities companies, the two most critical financial intermediaries in China’s stock market. Our results demonstrate that banks indeed serve as marginal investors and influence stock market efficiency primarily through the equity capital constraint channel. Furthermore, we find that the bank capital ratio factor significantly explains stock mispricing in China, with the single-factor model based on bank equity capital producing substantially smaller pricing errors compared to traditional multi-factor models.
  • 详情 Synergistic Driving Mechanisms of Full Guaranteed Purchase and Tradable Green Certificates Systems on Renewable Energy Integration
    The Full Guaranteed Purchase System began to replace the subsidy system as the core policy for promoting renewable energy integration, designating grid companies as the sole entity responsible for the physical integration of renewable energy. Meanwhile, the Tradable Green Certificates system provides environmental benefits for renewable power generators through market mechanisms. Therefore, exploring the strategic choices of various entities under the dual policy interventions, and uncovering the mechanisms for realizing electricity energy value and green value under different integration models, is of great significance for advancing China’s renewable energy integration. Based on China’s actual conditions, this study integrates the features of both policies and constructs a three-party evolutionary game model involving government, power generators, and grid enterprises to simulate their interactions and identify key factors influencing strategic choices. The results show that active government regulation effectively encourages positive strategies from both generators and grid companies, and that active power integration by grid companies further promotes green power generation. A “stepwise complementary” relationship exists among reputation gains, reputation losses, and regulatory costs: higher reputation gains can offset decision-making resistance arising from increased regulatory costs. Green power generation costs and innovation costs have significant negative effects on strategic choices, while the guaranteed purchase price has a significant positive effect on generators’ active strategies. The penalty parameter plays a key positive role in grid companies’ active strategies, and the guaranteed purchase price significantly influences their active integration behavior. This paper provides recommendations for motivating all entities actively participate in the consumption process.
  • 详情 Carbon Emission Trading Policy, Supply Chain Linkage, and Firms’ Bank Loans
    This paper examines the spillover effects of China’s Carbon Emissions Trading Scheme (CETS) on non-regulated firms’ bank loans. Using a sample of Chinese A-share listed firms and a staggered difference-in-differences design, we find that suppliers experience a significant decline in bank loans when their customers are included in the CETS. This effect is driven by reductions in firms’ cash flow and customer concentration. The negative effect of downstream CETS on suppliers’ bank loans is attenuated for suppliers with better environmental performance, more comprehensive carbon disclosure, and closer geographic proximity to customers. We also find that, in response to reduced bank credit, firms rely more heavily on trade credit. Overall, this study sheds new light on the unintended financial consequences of CETS policy on non-regulated firms.
  • 详情 Can Judicial Deterrence Curb Corporate ”Say-Do Discrepancies”? —A Quasi-Natural Experiment from the Environmental Courts
    Against the backdrop of global green development and China’s sustainable economic transition, many firms exaggerate green-transition disclosures to cater to national strategies and capital market preferences, leading to a severe "Say–Do Gap". Based on signaling theory, this study uses the phased establishment of environmental courts in 208 prefecture-level cities as a quasi-natural experiment, adopting a staggered DID design with 2007–2023 panel data of Chinese A-share listed firms for empirical tests. Results show widespread corporate green pandering, with improved disclosure not translating into actual carbon reduction. Environmental courts effectively curb this behavior, with environmental litigation risk as the core mediating channel. Heterogeneity tests reveal stronger deterrence in regions with weaker regulation/heavier pollution and polluting firms with stronger environmental technology. This study enriches literature from a judicial deterrence perspective and provides implications for substantive corporate green transition.
  • 详情 Carbon Markets in China: Strategic Interactions and Corporate Adaptation
    Examining a cross section of seven regional Emission Trading System (ETS) and thenational ETS in China, we explore the interplay between firms and governments. We find heterogeneous adaptation among firms. Firms in regions anticipating stringentpolicies reduce emissions and invest in decarbonization technology, whereas expecta-tions of lenient policies lead to increased emissions. Meanwhile, governments set upmore stringent carbon policies when firms decarbonize more proactively. The resultsare robust to allowance allocation policies, such as cap-and-trade or tradable perfor-mance standards. Our findings underscore the importance of strategic interactionsbetween firms and governments in decarbonization.
  • 详情 Slow Progress or Quick Success: Does green credit facilitate the service transformation of Chinese manufacturing enterprises?
    Breaking away from being “large but not strong” and accelerating the internal “dual circulation” reform to integrate the manufacturing and service industries is a daunting challenge. This study examines how environmental regulations and financial instruments can simultaneously drive servitization evolution and green transformation. Utilizing the Green Credit Guidelines (GCG) policy rollout by China in 2012 as a quasi-natural experiment, we analyze 2007-2021 data from A-share listed manufacturing corporations through DID model to evaluate the policy ramifications and investigate servitization direction. The results show that: (1) While GCG generally promotes overall servitization, it biases firms toward traditional rather than modern servitization pathways. (2) Contrary to typical innovation compensation effects, GCG induces short-sight in managerial decisions, favoring quick wins over innovation-driven progress. These results highlight why firms have tended to advance traditional servitization while constraining modern servitization efforts. (3) Heterogeneity analysis shows stronger policy impacts in firms with domestically-oriented executives and domestic ownership, where both overall and traditional servitization are significantly enhanced.
  • 详情 Understanding Users’ Intention to Reuse Parking Reservation Systems in China:Considering Users' Behavioral Uncertainty
    The parking reservation systems (PRS), as an intelligent system, was adopted to address urban parking difficulties. However, the parking reservation system has not been widely adopted in China due to the reasons such as the imperfect system and the uncontrollable parking behaviour of users. This study examines the impact of users' non-compliant behaviour on intentions to reuse PRS. Non-compliant behaviours include not arriving or leaving parking spaces not as scheduled, negatively affecting subsequent users. The Technology Acceptance Model (TAM) was expanded by adding perceived risk, social influence, and behavioral attitude. A survey involving 702 PRS users from multiple Chinese cities was conducted. Structural Equation Modelling (SEM) was used for analysis Results show that perceived risk—such as occupied reserved spaces and extra fees from time deviations—significantly reduces behavioral attitudes and reuse intentions. Conversely, perceived usefulness, ease of use, and social influence positively influence both attitudes and reuse intentions. Importantly, the findings highlight that behavioral uncertainty, particularly users’ deviations from scheduled parking times, is a critical source of perceived risk that undermines trust and long-term engagement. Effectively managing this uncertainty through improved system flexibility and reliability is therefore essential to promoting the sustained adoption of PRS.
  • 详情 Beyond Democratic Assumptions: Altruism, Political Citizenship and State-Society Relations in Contemporary China
    This study challenges democratic citizenship theory by examining altruistic behaviour in authoritarian China. We find that financial resources influence prosocial engagement primarily through psychological mediators such as long-term planning and self-discovery, rather than directly providing material means for participation. Communist Party membership shapes specific domestic ideological orientations, but not attitudes toward market regulation or income equality, while cultural tradition emerges as a stronger predictor of certain political attitudes than party affiliation. Cluster analysis identifies three distinct citizen profiles: (1) future-oriented altruists; (2) status-driven contributors; and, (3) short-termpragmatists, revealing motivational heterogeneity within authoritarian publics. These findings suggest that authoritarian citizenship operates through psychological mediation and plural motivational pathways fundamentally different from democratic societies, with potential applicability to other single-party regimes where states actively structure prosocial behaviour. The study contributes to comparative authoritarianism literature by theorizing how regime type moderates the relationship between socio-economic resources, political identity, and civic engagement.
  • 详情 Environmental data-driven dynamic Bayesian network for risk performance evolution in China's coastal shipping
    With the rapid development of the global shipping industry, maritime traffic continues to grow, and maritime traffic risks are becoming increasingly prominent, posing serious threats to economic development, the ecological environment, and public safety. In this context, this study develops an environmental data-driven dynamic Bayesian network (DBN) model to simulate the dynamic evolution process of maritime traffic risks from the massive data of complex shipping systems. Firstly, based on the systems theoretic accident model and processes (STAMP) accident causation analysis framework, risk influencing factors (RIFs) are identified through the analysis of maritime accident report systems. Secondly, addressing the dynamic nature of maritime risks, a novel transition probability matrix (TPM) learning mechanism integrating environmental data is proposed, constructing a DBN model capable of characterizing temporal risk performance. Finally, a case study of typical routes along the Chinese coast reveals that risk performance evolution exhibits significant spatiotemporal heterogeneity across sea areas, with the East Sea and South China Sea regions being the most prominent. Their fluctuations are highly correlated with seasonal meteorological and hydrological changes, and the distribution of accident risks is also closely associated with extreme weather events such as typhoons. Sensitivity analysis validates the model's reliability. This study provides a quantitative tool for the dynamic risk management of intelligent shipping systems and offers policy insights for intelligent maritime transportation safety regulation.
