长江三角洲城市群循环经济发展水平的空间格局分析

开展循环经济，走可持续发展道路是提升长江三角洲城市群全球竞争力的必由之路。在参考大量城市循环经济评价指标体系的基础上，从社会经济发展、减量化、再循环再利用、生态环境质量4个方面，选取18项代表性指标，建立了城市循环经济水平评价指标体系。采用中国城市统计年鉴2006年的统计数据，运用层次分析法（AHP）确定各指标的权重，计算得出长江三角洲城市群各城市循环经济综合指数，并对其空间格局和影响因素进行分析。研究结果表明：①各城市循环经济发展水平差异显著；②各城市循环经济发展水平由城市群外围向中心逐渐递增；③随着人均地区生产总值的上升，循环经济水平呈不规则“W”变化。循环经济发展政策、产业结构、经济发展水平和乡镇企业的规模和数量是影响长江三角洲城市群各城市循环经济发展水平的主要因素。最后，对长江三角洲城市群循环经济发展提出了几点对策建议.

ANALYSIS ON THE SPATIAL STRUCTURE OF RECYCLING ECONOMY OF URBAN AGGLOMERATION IN THE YANGTZE RIVER DELTA

Construction of recycling and sustainable developing economy is the inevitable method to enhance the global competitiveness of the urban agglomeration.In this article,with reference to mass existing system of evaluation on urban recycling economy, the authors established a new evaluating system,which focuses on the social economy development,resource reducing，recycling and quality of environment in 18 representative indices.Under this system,after adopting the data of China Urban Statistics Yearbook(2006),applying the Analytic Hierarchy Process (AHP) method to measure the weight of each index,the authors concluded a comprehensive index of comprehensive indices of recycling economy of urban agglomeration in the Yangtze River Delta.Then,the spatial structure of recycling economy and influential factors was deeply analyzed.The result of the research suggests that: ①The difference of recycling economic level among various cities is remarkable;②The recycling economical level appears to be a trend of gradually diminishing from the center to the periphery; ③Along with the per capita gross area product rising,the recycling economic level assumes irregular “W” mode.The significant influencing factors are the recycling economy's policy,the industrial structure,the level of economical development and the township enterprise's scale and amount.Finally,some strategic suggestions on the development of recycling economy of Urban Agglomeration in the Yangtze River Delta have been put forword.
