Community-based natural resource governance is often promoted in the name of sustainability, yet long-term outcomes remain elusive. This study examines the impact of various types of trust as the underpinning factor for the long-term resilience of collaborative resource governance. Using a four-type trust framework, dispositional, affinitive, rational, and procedural, the study compares trust trajectories across the prior to-, during-, and post-project phases of matsutake mushroom management in two communities within the S National Protected Area, Yunnan Province, China. Drawing on qualitative interviews and comparative case analysis, the study finds that while neither community sustained co-management mechanisms in full, X Village retained partial continuity through embedded procedural and rational trust. In contrast, Y village experienced accelerated institutional decline after project withdrawal, as market changes and weak enforcement undermined collective norms and trust in formal structures. These findings underscore that institutional resilience is shaped not only by institutional design but also by the evolution and interaction of trust types over time. By tracing trust trajectories across project stages, this study contributes a micro-level explanation of how trust mediates post-project governance outcomes. It emphasizes the importance of layering trust and embedding it within local social and institutional practices. The findings highlight the need to consider how co-management strategies can support trust continuity after project withdrawal, particularly by acknowledging the underlying structural conditions that shape trust resilience.

This study develops a comprehensive methodological framework for identifying and quantifying investor echo chambers in online stock discussion forums. Motivated by a dynamic model of endogenous echo chamber formation, which formalizes how investors optimally allocate attention and update beliefs under cognitive and informational constraints, we construct a two-layer multiplex investor network that integrates common-attention similarity and semantic similarity to jointly capture the informational and cognitive linkages among investors. This framework enables the systematic examination of how shared information sources and convergent opinions emerge within investor communities. We compute both community-level and individual-level (node-level) echo-chamber intensity by integrating measures of social homophily, semantic reinforcement, and community insularity. At the firm level, we further aggregate these micro-level indicators using attention-weighted indices, community concentration (HHI), and semantic polarization metrics to characterize how echo-chamber dynamics manifest in firm-related discussions. In addition, we propose a general empirical panel framework to examine the relationship between investor echo-chamber intensity and firm-level outcomes. Overall, this paper provides a methodological foundation for the broader Investors’ Echo Chamber Project, offering scalable tools for network-based behavioral analysis and laying the groundwork for future research linking online social dynamics, financial market efficiency, and corporate decision-making.

The role of institutional investors in the development of Environmental, Social, and Governance (ESG) criteria lacks consensus in the academic community. This study utilizes a quasi-natural experiment involving Chinese mutual funds that have signed the United Nations Principles for Responsible Investment (UNPRI) to investigate whether institutional Investors’ ESG investment commitments can significantly reduce ESG rating disagreement among the companies in their portfolios. We first find that companies held by ESG commitment institutional Investors exhibit less disagreement in ESG rating compared to those held by Non-ESG commitment institutional Investors. we then show that institutional Investor’ ESG investment commitment influence ESG rating disagreement by enhancing the quality of ESG disclosure and attracting external ESG attention. We further discover that institutional investors’ ESG investment commitments significantly mitigates the ESG rating disagreement among domestic ESG rating agencies and firms with a higher level of corporate governance.

Fighting global warming has become a vital requirement for environmental sustainability. Green finance has gained popularity as a promising mechanism for transitioning to a lowcarbon economy. Thus, this paper investigates whether excess green financing increases renewable energy capacities and enhances environmental quality from 1992Q1 to 2020Q4 in China, one of the major CO2 emitters. We primarily used the method of moments-quantile regression with fixed-effect models. First, we found nonlinear U-shaped impacts of green finance on wind power capacities in all Chinese regions, thermal power capacities in the Western and Central areas, and hydropower capacities in Eastern China, respectively. Second, we confirmed an inverted U-shaped impact of green finance on CO2 emissions in the Eastern region but U-shaped effects in the Western and Central regions. The impacts of green finance were asymmetrical due to the heterogeneous distributions of renewable energy sources and environmental quality within and between regions. Green finance mostly improved environmental quality when certain conditions and thresholds were met. Third, green finance had substantial marginal effects on environmental quality in the least polluted provinces (Q.20) in Western China and the most polluted provinces (Q.80) in Eastern China. Finally, there were heterogeneous effects of oil prices, urbanization, foreign direct investments, and trade openness on renewable energy consumption and environmental quality across Chinese provinces. Accordingly, this study provides some policy recommendations for China’s sustainable development, a key example from which the international community can adjust its green policies.

This paper examines the causes and consequences of venture capital (VC) stage financing. Using information about the geographic location of an entrepreneurial firm and the distance between the VC investor and the firm, I distinguish between three different hypotheses: the monitoring hypothesis, which argues that the VC staging and monitoring of entrepreneurial firms are substitutes; the hold-up hypothesis, which argues that staging is a mechanism for mitigating the hold-up problem between the entrepreneur and the VC investor; and the learning hypothesis, which argues that staging creates value through the real options generated by learning by VC investors. My analysis of the causes of stage financing suggests that VC investors located farther away from an entrepreneurial firm tend to finance the firm using a larger number of financing rounds, shorter durations between successive rounds, and investing a smaller amount in each round; however, VC investors’ propensity to stage is independent of whether or not the firm is located in a close-knit community. My analysis of the consequences of stage financing suggests that VC staging positively affects the entrepreneurial firm’s propensity to have a successful exit, operating performance in the IPO year, and post-IPO survival rate, but only if the firm is located far away from the VC investor; however, the entrepreneurial firm’s performance is independent of whether or not it is located in a close-knit community. Overall, the evidence supports the monitoring hypothesis, but does not provide any support for the hold-up or learning hypotheses.
