摘要
水作为不可再生、无可替代的战略资源,保护水环境具有重要的意义。地方政府、企业和公众作为水环境保护的参与主体,本文建立了三者之间的博弈演化模型。当水环境带来的收益较大,公众进行监督的舆论压力亦较大,则地方政府、企业和公众均可能实施正向策略。进一步解析博弈三方实施正向策略时,各参数对博弈三方的影响,结果表明:地方政府投入适当的成本和财政补贴、公众对政府的舆论监督,都将使地方政府实施严格管理;水环境给公众带来更多的环境收益时,公众对水环境保护的监督积极性更高;若企业投入水环境治理的成本较大,企业不违规排污策略的意愿度有所减小,随着水环境损失的增加,企业表现出更为强烈的进行水环境保护的行动意愿。可见,公众参与有利于水环境的保护;地方政府通过增加财政补贴,缓解企业进行水环境保护时投入的成本压力,可提高企业对水环境保护的意愿度。
The protection of water environment is of great significance.This paper established the game evolution model among the local government,enterprises and the public which are the main participants of water environmental protection,and systematically analyzes the decision-making evolution process of local government,enterprises and the public.When the benefits of water environment are great and the pressure of public opinion brought by public supervision is also great,the three parts of the game may implement positive strategies.This paper further analyzes the influence of each parameter on the three parts of the game when they implement the positive strategy.The proper input cost and financial subsidy of local government,and the public’s supervision of the government will make the local government implement strict management.When the water environment brings more environmental benefits to the public,the public has higher supervision enthusiasm for water environment protection.If the cost of water environment treatment is high,the willingness of enterprises to implement the"no illegal pollution discharge strategy"will be reduced.With the increase of water environment loss,enterprises show stronger willingness to protect water environment.Therefore,the proper participation of the public is conducive to the protection of water environment.By increasing financial subsidies,local governments can alleviate the cost pressure of water environmental protection for enterprises,and improve the willingness of enterprises to protect the water environment.
