环境友好行为、信息公开与庇古税研究

在信息传播迅速的现代社会,环境友好行为日益成为环境规制的重要考量因素,环境友好行为更将借助信息公开这一新型环境规制手段而发挥更大的作用。为了实现节能减排与低碳经济发展,当环境友好行为渗透于排污费等常规的环境规制工具的实际应用中,环境规制政策应当精心设计。当涉及环境友好行为时,庇古税有何不同?在包括外部性的古诺模型分析框架中对该问题进行研究,得到结论:①消费者对污染排放的反应越强烈,污染排放量越小;②给定环境友好行为,次优排污费在竞争性条件下等于污染边际损害,垄断条件下小于污染边际损害;③市场结构、污染治理成本不变时,环境友好行为是造成排污费小于污染边际损害的一个因素。

Research on Environment-Friendly Behavior, Information Disclosure and the Pigouvian Tax

In the modern society with rapid information dispersion,environment-friendly behavior gradually becomes a substantial factor in the environmental regulation,and it will play a more important role with the help of information disclosure which is a new tool of environmental regulation.To accomplish energy conservation,emission reduction and low-carbon economy development,an environmental regulation policy should be well-designed in order to cope with the interpenetration of environment-friendly behavior into the application of usual regulation tools.Is there any difference in the Pigouvian tax considering the environment-friendly behavior? Employing the Cournot model,the issue is studied,and the following conclusions are drawn: firstly,the amount of pollution discharge decreases with more intense reaction of consumers to pollution discharge,secondly,second-best Pigouvian tax equals marginal damage in competition and less than that with market power,given environment-friendly behavior,thirdly,the environment-friendly behavior is another factor reducing the Pigouvian tax,given the market structure,and abatement cost.
