基于灰色关联模型的江苏省农村生态文明建设水平研究

A Study on Construction Level of Rural Ecological Civilization in Jiangsu Province Based on Grey Correlation Model

[目的]诊断农村生态文明建设水平,为相关政策制定提供一定的参考依据。[方法]建立基于PSR模型的农村生态文明建设水平评价指标体系,采用灰色关联模型诊断江苏省农村生态文明建设水平。[结果]江苏省农村生态文明建设水平具有区域差异,其中苏州市最高,农村居民恩格尔系数、节能环保公共财政支出、对生活污水进行处理的行政村数量比例、单位耕地农药负荷、每万人口卫生机构床位数是农村生态文明建设水平提升的关键制约因素。[结论]基于PSR模型的评价指标体系能更准确地反映农村生态文明各要素之间的关系;灰色关联模型能有效挖掘农村生态文明建设存在的具体问题,适合用于农村生态文明建设水平诊断。

[Objective] This paper aimed to diagnosis the level of rural ecological civilization construction, to provide some references for policy making.[Methods] An evaluation index system for rural ecological civilization construction level was constructed based on pressure-state-response（PSR） model, and an empirical analysis was conducted in Jiangsu Province using grey correlation model.[Results] The level of rural ecological civilization construction had regional differences in Jiangsu Province, and the highest of it was found in Suzhou City. Crucial constraints on the improvement of rural ecological civilization construction level include the Engel coefficient of rural residents, the public expenditure on energy conservation and environmental protection, the proportion of administrative villages in the treatment of domestic sewage, the pesticide load per unit of cultivated land, and the number of beds per ten thousand population of health institutions.[Conclusion] These methods are suitable in the diagnosis on the rural ecological civilization construction level because the evaluation index system based on the PSR model can accurately reflect the relationship among various elements of the rural ecological civilization. Furthermore, the grey correlation model can discover more specific problems existing in the rural ecological civilization construction.
