摘要:Since the early 1970s an increasing number of books and articles in the field of environmental economics have been published. The focus of these publications does not show a uniform pattern, but is oriented to different issues: (a) descriptive analyses and models for environmental impacts of economic activities; (b) theoretical contributions to an understanding of environmental-economic questions based on traditional welfare-theoretic notions; (c) predictive models for gauging future environmental impacts of economic developments and for gauging economic impacts of abatement policies; (d) operational policy-oriellted models dealing with either methodologies or practical case studies.
