Research on Effects of Environment Policies and Systems on Environmental Protection Industry

Abstract

Environment polices/systems play vital roles in and are motive powers for the development of environmental protection industry. In order to delve into the facilitating influences of different environment polices/systems at various development stages of the environmental protection industry, the paper analyzes the forces acting on the development of environmental protection industry in combination with the theory of industrial economics and features of the environmental protection industry. Environment polices/systems facilitating the development of environmental protection industry are divided into three major categories: industry demand based, industry supply based and industry regulation based, which are further classified into 24 items. The Delphi method and single factor evaluation model are adopted for the evaluation of the influence degrees imposed by environment policies/systems at different stages of the environmental protection industry on the industrys development and for empirical analyses on the urban sewage treatment industry.
