农业保险与乡村产业振兴耦合协调发展是推动农业高质量发展的重要因素。通过面板向量自回归模型、耦合协调度模型和障碍度分解模型，本文分析了2007—2021年西南地区33个地级（及以上）城市农业保险与乡村产业振兴的动态互动关系、耦合协调度的时空演化及障碍因子。研究发现：二者存在逐渐加深的相互促进关系。二者的耦合协调度逐年提升，但区域差异显著；区域间差异是总体差异的主要来源，区域内矛盾日益凸显；空间收敛模型结果显示，西南地区整体及各省域均不存在显著的σ收敛，但均存在显著的β收敛，尤以贵州收敛速度最快。影响二者协调发展的核心障碍包括农业保险规模水平的明显短板、“量”与“质”的系统性失衡以及乡村产业结构合理化、机械化与绿色发展水平的局限。据此，本文就两系统自身及耦合协调发展的推进路径提出建议。

人口老龄化是我国今后相当长一个时期的基本国情，作为《宪法》第四十五条所规定的“基本公共服务”内涵的应有延伸，人居环境的适老化改造事关老年人“老有所居、居有所安”的基本民生保障，也是实现老年人居家养老与医疗照护的重要基础。但我国《民法典》关于建筑物区分所有权治理秩序的规定尚不翔实，实践中既有建筑共有部分的适老化改造囿于决策程序僵局、改造费用规范性指引不足、不利影响补偿机制缺失等多重困境，无法适恰既有区分所有建筑物共有部分的适老化改造需求。原居养老与居家安全危机之间的对立矛盾亟需整合共有规则要素，通过统筹老旧小区的专有与共有治理效能、功能提升与空间协调、利用现状与未来需求三对交互关系，形成体系化的治理机制设计，以积极应对人口老龄化国家战略，破除老年人群体居住保障的低水平均衡陷阱。

在人口老龄化持续加深的背景下，我国养老社会保障体系面临筹资放缓、支出刚性上升与区域负担失衡等多重压力，财税可持续性风险由局部性问题逐步演化为系统性挑战。本文立足财税治理视角，在梳理我国养老社保财税支撑现状的基础上，围绕筹资端、支出端和长期运行三个层面识别主要风险，并从制度设计、政策协同、人口结构变化及征管监管机制等方面剖析风险成因。研究进一步结合德国、日本、美国及北欧国家的实践经验，提炼出“法治化筹资、参数化调节、数据化征管、协同化治理”的共性路径。基于此，本文提出优化养老筹资机制、重构中央与地方支出责任、完善风险预警体系、强化财税政策协同的治理方案。研究认为，养老财税风险防控的关键不在单一政策加码，而在于建立跨周期、可预警、可调节的制度框架，实现养老保障公平性与财政可持续性的动态平衡。

在人口老龄化加剧与生育率持续走低的背景下，商业养老保险作为多层次养老保障体系的关键补充，其发展面临居民参与率低、供需失衡的挑战。不同于传统经济理性视角，该研究从文化观念切入，探讨传统生育伦理对居民参保决策的影响。基于中国家庭金融调查（CHFS）2017年数据发现，传统生育观念显著抑制商业养老保险参与，且这一效应在西部地区及低教育水平群体中更为突出。机制分析表明，传统观念通过削弱金融信任和降低财经信息关注度间接阻碍参保行为。研究为破解养老金融“有限参与”困境提供了文化解释，对优化养老保障政策具有参考价值。

Purpose The study investigates the impact of government intervention policy of capital markets (“National Team”) on firms’ sustainable management, i.e., green mergers and acquisitions (GMAs) in China, aiming to understand how such interventions influence corporate investment activities amidst a growing focus on green transition. Design/methodology/approach The research employs a dynamic analysis of quarterly data from Chinese companies (2014 Q1 to 2022 Q4), utilizing identified strategies, such as double machine learning-DID and multiple panel data regressions to assess the effects of government intervention on GMAs, and examines potential economic channels like liquidity, market stabilization, and informativeness. Findings The study finds that increased government intervention via direct stock purchases significantly boosts both the number and amount of GMAs, with economic significance of 23% and 45%, respectively. It identifies liquidity, market stability, and informativeness efficiency as underlying economic channels for this effect. Practical implications The findings suggest that government interventions can enhance corporate investment in green sectors, guiding firms to align strategies with sustainability goals. This can inform policymakers regarding the effectiveness of direct stock purchases in fostering a green economy, especially for large emerging countries. Social implications By promoting GMAs, government interventions contribute to green innovation and energy transition, ultimately benefiting society through enhanced environmental sustainability and compliance with eco-friendly regulations. Originality/value This research uniquely documents the direct effects of government stock purchases on corporate green financial activities, particularly GMAs, in a Chinese context characterized by tight credit, thereby expanding the understanding of government intervention in emerging markets.

This study investigates the impact of RegTech adoption in the M&A regulatory review process on deal performance. Leveraging the staggered implementation of the SOEs Online Supervision System (SOSS) by China’s State-Owned Assets Supervision and Administration Commission (SASAC) across its central and 31 provincial offices from 2018 to 2021, we find that SOSS directly enhances SASAC’s decision-making efficiency and improves its capacity to screen and approve higher-quality M&A deals. More importantly, SOE-led M&A transactions exhibit higher announcement returns as well as improved long-run stock and operating performance following the system’s implementation. The positive impact of SOSS is more pronounced for acquirers with stronger technological infrastructure, in transactions characterized by low transparency and weak governance, and in provinces with more stringent external scrutiny. Overall, by addressing regulator-firm information asymmetry and reinforcing managerial accountability, SOSS improves regulatory effectiveness in overseeing major investment activities among SOEs.

This paper examines how auction design can unintentionally facilitate bidder collusion in land market. Departing from the dominant view that attributes low land concession revenues to corruption, we highlight how features of auction structure enable bidder-side collusion, suppressing sale prices. Using a dataset of land auctions from 15 Chinese cities (2006–2016), we find that two-stage (listing) auctions are significantly more susceptible to collusion than one-stage formats. Empirical evidence shows that sales concluding at the (secret) reserve price occur disproportionately in two-stage auctions, even after controlling for land and market characteristics. We argue that the transparency and sequencing of two-stage auctions, while designed to enhance fairness, inadvertently reduce monitoring costs and facilitate tacit bidder coordination. Our findings underscore the need to jointly consider auction format and reserve price policy in designing land sales to enhance market efficiency and mitigate collusion risks.

This study employs a Triple-Difference (Triple-DID) model, utilizing balanced panel data at the district level from Beijing, Shanghai, Shenzhen, and Hangzhou between 2018 and 2024, to critically evaluate the effectiveness of the Multi-School Zoning Policy (MSZP) in suppressing the capitalization of educational resources into housing prices and promoting educational equity. The research explicitly accounts for spatial and institutional heterogeneity as well as household strategic behavior.The results indicate that: (1) MSZP significantly reduced the average housing price premium associated with elite school districts by 15.2%, with the strongest effect observed in Beijing and the weakest in Hangzhou; (2) The policy's effectiveness diminishes as the spatial concentration of high-quality educational resources increases, highlighting persistent structural inequalities; (3) In areas characterized by resource monopolization and strong institutional inertia, the policy's suppressive effect on educational capitalization and its gains in educational equity are both constrained.The findings suggest that MSZP alone cannot fully overcome the "spatial lock-in" effect of high-quality educational resources. Achieving lasting equity requires complementary deeper institutional innovations, such as robust cross-district teacher rotation, transparent resource allocation mechanisms, and adaptive zoning algorithms. This research offers quantitative evidence for optimizing policy and institutional tools in the pursuit of comprehensive urban education reform.

We construct a Housing Purchase Intention Index (HPII) using the Baidu Search Index, which captures online search behavior directly reflecting households’ housing purchase intentions. We assess the predictive power of the HPII for the growth rate of housing transaction volume and further examine factors influencing housing purchase intention. The results show that the HPII has significant predictive ability and enhances real-time forecasting accuracy, highlighting the role of search behavior as a behavioral signal in the housing market. We also find that housing purchase intention is shaped by policy, economic, demographic, and supply factors. Specifically, purchase restriction policies exhibit an inverted U-shaped effect; moderate mortgage-rate hikes dampen purchase intention, while persistent increases may induce anticipatory buying. In addition, rising wages, increasing population concentration, and expanded residential land supply consistently strengthen housing purchase intention. These findings provide new behavioral evidence on the drivers of housing demand and underscore the value of search-based indicators for understanding household decision-making in the real estate market.

We construct the most comprehensive bankruptcy database of Chinese firms to date and document significant real effects arising from the establishment of specialized bankruptcy courts. Specifically, the recovery rate for unsecured creditors increases by 38.6 percentage points after the reform. This improvement is not driven by shorter case durations or lower direct bankruptcy costs, as intuition might suggest. Instead, it results primarily from greater efficiency in the discovery and disposal of assets during bankruptcy proceedings. The reform also increases the likelihood of reorganization and promotes capital infusion in such cases. Higher recovery rates generate broader spillovers: reductions in non-performing loans, expansion of unsecured lending by local banks, relaxation of firms’ financial constraints, shifts in capital structure and investment, and greater public willingness to file for bankruptcy when distressed.
