基于过度自信的企业发展低碳经济激励机制研究

在考虑企业过度自信的情况下,建立了企业发展低碳经济的激励机制模型并进行了系统研究。结果表明:政府的最优激励补贴与企业的风险规避度、外界不确定因素方差、努力成本系数负相关,与企业节能减排产出系数和过度自信水平正相关;当企业的过度自信水平满足一定约束条件时,政府的激励补贴强度以及期望环境收益都要大于企业完全理性时的情形;当企业的过度自信水平超过一定约束条件时,政府的最优激励补贴以及期望环境收益小于0;企业过度自信的容忍度与企业风险规避系数以及外界不确定因素正相关。

Study on Incentive Mechanisms of Low-Carbon Economy Development Based on Overconfidence

Considering enterprise overconfidence,it constructs a model for incentive mechanisms about low-carbon economy development and does a systemly research.The results show that the optimal government incentive subsidies are negative correlation with degree of business risk aversion,variance of the external uncertainties and effort cost coefficient.In the other hand,it is positive correlation with enterprise output coefficients of energy conservation and the level of overconfidence.When the level overconfidence satisfies a certain constraint conditions,the strength of the government’s incentive subsidies and expected environmental benefits is larger than the ones in the case business is in the fully rational.When the level of overconfidence is above of a certain constraint conditions,the government’s optimal incentive subsidies and expected environmental benefits is less than 0.Tolerance of overconfidence is positive correlation with the degree of business risk aversion and external uncertainty.
