This study investigates how environmental penalties affect the share prices of Chinese listed companies. By linking the share prices of listed firms to the full administrative environmental penalty records from 2015 to 2020, market reactions to 3602 environmental violations measured by cumulative abnormal return (CAR) are studied. We find that after an environmental penalty, the share price of the violator would decline significantly, but with a small magnitude in general. Our results provide empirical evidence that companies are paying some extra costs in the stock market for their environmental noncompliance in China, especially for environmental penalties with large fines, business bans, or those issued by high-level governments. Also, large, state-owned, and key emission unit companies are found to be less affected.  相似文献

Using a novel hand-collected sample including 159 industrial events that occurred between 2000 and 2020, we document that corporate social performance (CSP) generally acts as a halo effect mitigating the stock market drop following these events. These findings, robust to many alternative specifications, provide novel evidence shedding light on how corporate social capital acts as a mitigating device against the consequences of tail events. To the best of our knowledge, this is one of the first studies investigating the mitigation role of CSP in the aftermath of an industrial accident by analyzing a large global sample of industrial incidents. The practical and theoretical implications of our findings are at the bottom of that form of a socially normative corporate force embedded in social trust, smoothing managers' and stakeholders' interests together.  相似文献

Corporate social responsibility (CSR) disclosures have gained great attention in both the media and the academic community for many decades. In this paper, we shed light on three aspects of CSR disclosures, namely the determinants, measure and impact on firm value. Using a sample of 61 firms listed on the ADX for the period 2010–2014 and computing an eight‐item index, our results are conclusive and show that listing history, governmental sector, board size, financial leverage and firm size have a positive impact on CSR disclosures. By contrast, firm profitability, industrial sector and ownership concentration have no impact on the extent of CSR disclosures. Finally, CSR disclosures have no impact on firm value as proxied by market‐to‐book ratio. Our results remain unchanged using additional robustness checks. Our study highlights the three aspects of social disclosures (i.e. determinants, measure and impact) in an emerging stock market (ADX). Our findings will help investors when assessing firm value and policy makers when issuing CSR disclosure rules.  相似文献

中国粮食自给率研究——粮食、谷物和口粮自给率分析   总被引:6,自引:1,他引:6  
由于统计口径与计算方法的不同,粮食自给率的计算结果往往差异较大,得出的中国粮食安全的结论也大相径庭,从而引起国内各界的广泛争议。为了准确分析当前中国的粮食安全情势,避免误判对相关决策造成误导,有必要对粮食的统计口径和自给率计算方法进行分析研究。本文选用三种粮食自给率计算方法—定额统计法、流向统计法和消费统计法,测算中国2000-2016年的粮食、谷物和口粮自给率,并对结果进行对比分析。结果显示:(1)定额统计法计算结果容易造成失真,流向统计法与消费统计法计算结果较为准确;(2)谷物和口粮自给率更能反映中国实际的粮食供需情况;(3)中国谷物自给率在98%以上,口粮自给率高于100%。然而,随着工业化和城市化进程的加快,城市发展对土地的需求越来越大,这会造成耕地被侵占、粮食需求激增等严重问题,口粮生产仍然不能放松,建议未来调整农业结构,稳定小麦、稻米生产。  相似文献

The residential sector is the third largest sector of final energy use in Australian urban areas, accounting for about 12% of the country's total final energy consumption. What are the main determinants of energy consumption in the residential sector? This paper sheds light on this question by examining non-transport summer household energy consumption in Adelaide and Melbourne. Data were collected from a survey of 200 sample households and modelled according to a conceptual framework that not only emphasises household characteristics and housing stock characteristics but also controls the macro-environment factors. The findings reveal distinctive results in Adelaide and Melbourne. In Adelaide, household characteristics are the most important contributors in explaining non-transport household energy consumption. In Melbourne, the household characteristic as represented by income is important, but housing stock characteristics provide even more explanatory power. These findings contribute to the understanding of the factors that shape residential energy consumption and have policy implications in targeting household energy savings.  相似文献
