纵向关联市场、环境政策强度和中国环保产业的发展

Vertical Related Markets,Strength of Environment Policy and Development of Environmental Industry in China

在开放经济背景下,本文通过构建基于纵向关联市场的博弈模型分析环境政策强度对我国环保产业发展的影响。研究表明,由于中国和发达国家在环保产品生产技术和环境政策强度方面存在差距,当中国和发达国家环保产品的生产技术差距较大时,中国可以通过提高环境政策强度而获得更多环保产品的市场份额;环保产业的存在可以提高一国的环境政策强度,发达国家由于拥有更为先进的环保产业,其环境政策的强度将高于发展中国家。虽然中国政府提高环境政策的强度会在一定程度上削弱中国下游产业的出口竞争力,却可以减少对外国环保产品的依赖,有利于扶持本国环保产业的发展。

The paper constructs a vertical related industry model in open economy to analyze the impact of stringency of the environmental policy on the development of environmental industry in China.Results show that,there exist the gap of the technology of environmental goods and the environmental policy between China and the developed country,and Chinese government can strengthen the level of environmental policy to seize the higher market share of environmental goods when the technology gap is large;the environmental industry can improve the level of environmental standard,and the developed country can strengthen a higher level of environmental policy compared to the developing countries′because of the development of the environmental industry.Although it is a burden for a downstream firm if there is a strict environmental policy in China,such policy will support the environmental industry′s development and also reduce the dependence on the foreign environmental good.
