This study empirically examines the implementation of environmental policies and how government engagement impacts on a firm's environmental performance based on a sample of Chinese listed firms in the eight most polluting industries over a 10‐year period. The findings of the study demonstrate that government engagement, measured as ownership structure, is positively correlated with environmental performance, measured by environmental capital expenditure, for state‐owned firms, but no significant relation is found for non‐state‐owned firms. In addition, non‐state‐owned firms are more likely to perform better in terms of environmental investment after the 2006 enactment of a new policy explicitly linking environmental issues with political incentives to regional governments. This study also reports that corporate environmental performance impairs firm value for state‐owned firms but has no impact on firm value for non‐state‐owned firms, suggesting that investors negatively respond to environmental investments made by state‐owned firms as a result of government engagement/political pressure.

Due to the serious increase of environmental pollution in China, environmental regulations have become significantly stringent. Such regulations are playing an increasingly important role in the development of small enterprises (SEs) in China, especially in SEs' market entry. However, existing studies pay little attention to this issue. This paper investigates for the first time the effect of environmental regulations on SEs' market entry and the mechanism of environmental regulation effects in China. We consider two sets of panel data for the periods 2003–2010 and 2012–2015 in China. We also use the fixed effect model and the instrumental variable method to explore the role of environmental regulations in SEs' market entry. The results show that, overall, environmental regulations play a significantly positive and robust role in SEs' market entry. However, the mechanisms associated with the effect of environmental regulations on different innovative types of SEs differ. Environmental regulations promote the market entry of SEs with product innovation, but this impact is not significant for SEs with research and development (R&D) activities and R&D institutions. Our findings indicate that China's SEs prefer product innovation, which is a lower level innovative type, over R&D innovation, as a means to avoid the negative impact of stringent environmental regulations.  相似文献

I develop a contingent claims model to examine the impacts of managerial entrenchment on capital structure and security valuation. The analysis shows that managers’ self-interested leverage choices deviate significantly from the optimal leverages that maximize firm values, partially explaining the suboptimal leverage ratios observed empirically (Graham, 2000). Both the extent and sensitivity of the deviations are affected by firm characteristics, debt features and default solutions. The shareholder-manager conflicts over risk level and cash payout vary dynamically with a firm’s financial health. Managerial entrenchment does not mitigate the agency problems of debt since managers’ discretionary decisions on milking properties or asset substitution could be driven by incentives to increase their own utility.  相似文献

绩效和认可的理念在中国越来越被接受,并且很多企业开始在管理实践中用认可来激励和管理员工。有关绩效与认可的理念是先进和令员工振奋的,但在中国企业实施时,常常会产生"南橘北枳"的无奈。本文探讨了在中国的环境中,和合文化、"圈子"文化、中庸文化、面子文化、"集体本位"文化对于绩效和认可的影响,并且提出了对企业的建议。  相似文献

The main purpose of this paper is to provide additional evidence about the effect of discretionary current accruals on the pricing of IPOs. This paper seeks to discriminate between two alternative explanations for the prior findings: (1) behavioral biases coupled with limited arbitrage; and (2) the sample- and period-specific nature of the results in the prior literature. The IPOs from 1962 to 1998 were used to obtain the following results. First, there was not a negative association observed between discretionary current accruals and subsequent price performance for the 1926–1971 period. Second, analysis reveals that the pattern of cross-sectional evidence is inconsistent with the predictions made by behavioral theories. Third, in the 1972–1998 period, evidence of predictable negative performance attributable to IPO discretionary current accruals is limited to NASDAQ firms. These findings are difficult to reconcile with the explanation of behavioral biases coupled with limited arbitrage.  相似文献
