The development of the fresh-food e-commerce has led scholars to pay more attention to research on the agricultural product supply chain. This paper analyses the operation mode of the new O2O retail fresh supply chain by constructing the Stackelberg game model, takes the freshness and freshness-keeping efforts of fresh agricultural products as the main considerations, and analyses and compares the overall income of the supply chain under different decision-making modes. The results of the study show that: (1) In a centralized decision-making model, collaboration between suppliers and retailers online and offline can increase their respective revenues, and overall supply chain profits increase as the proportion of collaboration increases; (2) compared to decentralized decision-making, revenue-sharing contracts can increase the overall profitability of supply chain members and the supply chain when the revenue sharing factor is relatively high in the case of online and offline channel collaboration; (3) finally, the impact of revenue-sharing contracts on supply chain profitability is discussed through numerical analysis.

Understanding how the built environment relates to urban ecological resilience is essential for resilience-oriented planning in high-density cities. Using Wuhan, China, as a case study, we constructed a 1 km grid-based Ecological Resilience Index (ERI) by integrating ecosystem resistance, adaptability, and recovery, and we confirmed significant spatial autocorrelation in ERI. We then applied a Bayesian-optimized XGBoost model (v2.0.3) with block-based spatial cross-validation to improve robustness under spatial dependence, and used SHAP to interpret nonlinear, threshold-like patterns and interactions among predictors. The results indicate that building coverage ratio (BCR), nighttime light intensity (NTL), elevation (ELE), mean building height (MBH), and precipitation (PRE) were the most influential predictors of ERI. SHAP main effects indicate clear non-monotonic and threshold-like response patterns across key predictors. SHAP interaction analysis further suggests that, under high BCR, the SHAP interaction term tends to be positive when MBH is below approximately 10 m, whereas the interaction between high NTL and low MBV is predominantly negative. This study provides fine-scale empirical evidence to inform the optimization of three-dimensional urban morphology to support urban ecological resilience.

Drawing on prior research, this study analyzes panel data from listed companies (2013–2023) to examine how chairpersons’ local social connections affect corporate green innovation. Specifically, it explores how such networks provide access to resources and policy advantages through social capital, thereby shaping firms’ green innovation. The findings reveal that local chairpersons negatively affect firms’ green innovation. Firms led by local chairpersons undertake significantly fewer green innovation initiatives than those with non-local leaders. Moreover, ESG performance and a strong legal environment can mitigate the negative impact of local chairpersons on green innovation. In contrast, stable executive teams may alleviate the adverse effect of local chairpersons on corporate green innovation by curbing myopic managerial behavior and reinforcing a long-term strategic orientation.
