基于DEA-Tobit分析的企业社会责任投入与企业绩效研究

Research on the Corporate Social Responsibility Input and Corporate Performance based on DEA-Tobit Analysis

从投入产出的角度出发,基于DEA-Tobit方法对企业社会责任投入与企业绩效逐层回归改进,同时按照DEA截尾数据进行极大似然估计最优解的验证。对我国沪深两市制造业上市公司社会责任的绩效实证分析表明,企业社会责任优化结构投入总体上要比企业社会责任数量投入具有更明显的波动特征,同时企业慈善责任投入比企业伦理责任对企业绩效的提升具有更明显的波动。

From the perspective of input and output, the DEA-Tobit method is used to improve the corporate social responsibility input and corporate performance layer by layer, and the maximum likelihood estimation of the optimal solution is verified according to the DEA censored data. The empirical analysis of corporate social responsibility performance of listed manufacturing companies in Shanghai and Shenzhen stock market shows that the overall investment in corporate social responsibility optimization has more obvious fluctuation characteristics than the amount of corporate social responsibility. Meanwhile, corporate philanthropic responsibility input has more obvious fluctuation than corporate ethical responsibility in the improvement of corporate performance.
