控股家族涉入能促进企业履行环境责任吗？——基于中国A股上市公司的证据

基于2009—2017年我国沪深A股上市公司样本，比较了家族企业与非家族企业所履行的环境责任差异，研究了控股家族涉入对企业环境责任行为的影响。研究结果发现：家族企业比非家族企业更少地履行环境责任；在家族企业中，所有权比例的增加会显著降低环境责任水平，家族成员出任董事长会象征性地披露更多环境责任信息，家族涉入时间与环境责任之间总体上呈现出倒U型关系。进一步研究表明，家族企业会有选择地履行环境责任以维护家族声誉同时减少经济利益损失，控股家族涉入对环境责任的影响在创业型和非创业型家族企业中有所不同，在强制披露的企业中所有权比例对企业环境责任的消极影响会有所减弱。     

The impact of environmental regulation on Chinese spatial development

We examine the relationship between environmental regulation and spatial development in China. Exploiting changes in national pollution standards for three industries, ammonia, paper and cement, we measure the impact of environmental regulation on industry productivity. Our results suggest that national pollution standards do not affect industry productivity, but they reallocate productivity spatially. We show that regulated industries located in developing cities increase their productivity compared to similar industries in other cities. This means that environmental regulation affects the spatial distribution of technology in China and might influence long‐term spatial development by reducing geographical disparities.     

地方政府环境支出行为的空间策略互动研究*——传导机制与再检验

本文从理论和实证两个维度检验了地方政府环境支出行为的空间策略互动的传导机制。结果表明，环境支出存在明显的空间策略互动与时间滞后效应。其表现为相邻省级地区之间环保财政支出行为的互相模仿和路径依赖。外商直接投资和财政分权并不是导致地区间环境支出“逐底竞争”的直接原因。在构建多维度政绩考核体系来引导政府财政支出竞争的同时，建立地区间环境支出的协调机制和对外开放等途径，有利于实现均衡和绿色发展。     

Why Do Politicians Intervene in Accounting Regulation? The Role of Ideology and Special Interests

Politicians frequently intervene in the regulation of financial accounting. Evidence from the accounting literature shows that regulatory capture by special interests helps explain these interventions. However, many accounting rules have broad economic or social consequences, such as their effects on income distribution or private sector subsidies. The perception of these consequences varies with a politician's ideology. Therefore, if accounting rules produce those consequences, ideology plausibly spills over and explains a politician's stance on the technical accounting issue, beyond special interest pressure. We use two prominent U.S. political debates about fair value accounting and the expensing of employee stock options to disentangle the role of ideology from special interest pressure. In both debates, ideology explains politicians’ involvement at exactly those points when the debate focuses on the economic consequences of accounting regulation (i.e., bank bailouts and top management compensation). Once the debates focus on more technical issues, connections to special interests remain the dominant force.     

Security regulations,access to capital markets,and firm performance: Evidence from China

This study explores the cost of security regulations in China, where firms are required to meet a certain profitability benchmark before applying for permission to raise more equity via secondary equity offerings (SEOs). Using a difference-in-differences setting, we show that firms affected by the regulation (i.e., firms with high external financing demands (EFD) but profitability lower than the regulatory requirement) significantly underperform their counterparts, while unaffected firms do not. The affected firms’ performance decline increases (decreases) when the requirement of profitability is more (less) restricted. Consistently, the three-day cumulative abnormal return (CAR) of firms with high EFD is significantly negative (positive) when the regulation is tightened (loosened). Our study provides evidence on how the cost of regulation affects companies that have growth opportunities.     

Short-sale constraints and informational efficiency to private information: A natural experiment

Exploiting a regulatory change in short-sale constraints (Regulation SHO) as a natural experiment, this paper examines the effect of short-sale constraints on informational efficiency of stock prices to private information. I find that short-sellers act as informed traders prior to forthcoming analyst news and trade on negative private information. When short-sale constraints are relaxed for pilot stocks (treatment group), both trading volume and stock price sensitivity increase prior to the analyst announcement for bad news but not for good news, relative to that of nonpilot stocks (control group). The findings are consistent with the Diamond and Verrecchia model that predicts that short-selling increases the speed of adjustment of stock prices to private negative information. In the cross-section, the effect of Reg SHO is stronger in stocks of firms with weak and uncertain information environments (i.e., small firms and firms with high analyst forecast dispersion).

基于DEA-SBM模型的中国地板上市企业环境效率研究

考虑非期望产出,基于企业层面,根据2011-2016年数据,采用DEA-SBM模型与DEA-CCR模型对中国12家地板上市公司的环境效率与经济效率进行测算与比较。结果表明:2016年环境效率和经济效率测算结果显示不同地板上市企业运行效率存在差别;与经济效率相比,一些企业如北新建材、扬子地板,环境效率保持不变,一些企业如宜华生活、吉林森工和丰林集团,环境效率得到提升;还有一些企业如兔宝宝、升达林业和大自然家居等,环境效率则出现下降。考虑了非期望产出,中国地板上市企业整体环境效率均值低于经济效率均值,总体处于0.79~0.84之间。提出了政府应加强监管力度,地板上市企业应提高技术改进能力,建立完善社会责任信息披露机制的建议。     

自治、博弈与激励:我国农村人居环境污染治理的制度安排

基于中央政府、地方政府及农民的互动视角,采用博弈分析方法,系统考察了我国农村人居环境污染的逻辑机制。研究发现:我国农村人居环境污染的根源在于规制失灵;农村人居环境公共资源的“公地悲剧”不是必然现象,可以在农民之间建立一种自实施的自治机制,避免导致“公地悲剧”;由于利益目标的差异,中央政府与地方政府之间的激励问题、地方政府与农户之间的博弈行为,导致了农村人居环境规制失灵。研究启示是,制度的建立健全是农村人居环境治理顺利推进的保障,更将有利于乡村振兴战略的实施以及我国农村的可持续发展。
