Resear ch Progr ess on the Eco- Environmental Effect of Industry Agglomer ation in City Group
城市群地区产业集聚的生态环境效应研究进展

Industry agglomeration is a deep impulse force to the evolvement and the spatial expansion of city groups. Research on the eco-environmental effect of industry agglomeration in city groups has an important meaning regarding the construction of resource-conservative and environment-friendly city groups and the promotion of their competitiveness. The paper reviewed domestic and international research progress on theories, methods and practices in eco-environmental effects of industry agglomeration in city groups, pointed out the weak side of current study in this field and prospected main research directions in the future. Studies showed that the eco-environmental problems of industry agglomeration in city groups have received universal attention. Study on the influence mechanism and the effect which the industry agglomeration in city groups has on eco-environment has been held extensively in different aspects from industry sectors, industry structure, industry layout and industry cluster. And countermeasures to realize coordinated development of industry agglomeration and eco-environment in city groups are also discussed. Quantitative analysis methods, including emergy analysis, ecological footprint, system dynamic model, artificial neural network analysis method, input-output method, grey system analysis method and multiobjective programming method, have been applied to evaluating the eco-environmental effect of industry agglomeration in city groups, as well as analyzing, simulating and predicting the correlation between industry agglomeration and eco-environment in city group. In current research, theoretical studies and approach applications are still insufficient, and the research system is still not formed. In the future, the theory research based on spatial characteristics of city groups should be enhanced, and multi-disciplinary merges, enrichment of research approaches and technical methods and the integration with practice should also be strengthened.
