我国环保产业关联效应的投入产出分析

本文通过对比2007年与2012年投入产出表中环保产业与国民经济42个产业部门间的关联程度及结构的变化,分析得出环保产业的发展现状及产业关联结构有所优化。"环保产业不环保"的现状已有一定的改善,而"环保产业不服务于环保"的现象仍有碍于环保产业投资效率的进一步提升,大部分环保投资仍在中间生产过程中被消耗,产业生产效率水平较低。因此,政府应通过扩大环保技术投资、强化环境规制等政策打好产业组合拳,促进社会资本投资在加强环保产业内部竞争方面的综合作用,从而提高环保产业自身的价值创造能力,促进环保投资效率的提高。

Input-output Analysis on the Correlation Effect of Environmental Industry in China

The associated level and structure between environmental industry and 42 industrial sectors of national economy in the input-output tables between 2007 and 2012 were compared in this paper. Then the development status of environmental industry was obtained and its correlation structure with other industries has been optimized. The situation that "environmental industry is not environmental friendly" has been improved. However, the phenomenon that "environmental industry does not serve the environmental protection" still exists, which hinders the environmental industry to further enhance its investment effciency. As most of the environmental investments are consumed in the process of production, the industrial production effciency level is low. Therefore, the government should expand the environmental protection technology investment and strengthen the environmental regulation, promote the comprehensive effect of social capital investment on strengthening the internal competition of environmental protection industry, and thereby improve its own value creation ability and promote the effciency of environmental protection investment.
