基于物元分析法的农村社区环境建设绩效诊断

目的] 诊断农村社区环境建设绩效水平及其制约因素，为提高农村社区环境建设绩效水平提供参考依据。方法] 采用PSR模型、物元分析法和改进的熵值法诊断了江苏省农村社区环境建设绩效水平。结果] 2006—2019年江苏省农村社区环境建设绩效水平不断提高，农村社区环境建设绩效水平等级经历了“较差—良好”的演变历程，但2019年“良好”等级关联度很弱；环境卫生投入占市政公用设施投入比例、节能环保公共财政支出、对生活污水进行处理的行政村比例、化肥施用强度、农药使用强度、农用塑料薄膜使用强度、单位GDP能耗等是农村社区环境建设绩效水平提升的关键制约因素。结论] 为有效提高农村社区环境建设绩效水平，应进一步健全农村社区环境建设多元化投入机制，加强农村生活污水治理，有效改善农业生态环境，推进化肥农药减量增效，加强农用塑料薄膜污染治理，统筹推进高质量发展，合理提高能源资源利用效率，有效降低单位GDP能耗等。

Diagnosis on Performance of Rural Community Environment Construction Based on Matter Element Analysis

Objective] The performance level and its obstacle factors of rural community environment construction were analyzed, in order to provide a basis for improving the performance level of rural community environment construction.Methods] The PSR model, matter element analysis and improved entropy method were used to diagnose the performance level of rural community environment construction in Jiangsu Province.Results] From 2006 to 2019, the performance level of rural community environment construction in Jiangsu Province improved gradually from poor to good, but the coefficient of the correlation of the assessed rank for class of good was very weak in 2019. The proportion of environmental sanitation investment in municipal public facilities, public financial expenditure for energy conservation and environmental protection, proportion of administrative villages for domestic sewage treatment, application intensity of chemical fertilizer, use intensity of pesticide, use intensity of agricultural plastic film, energy consumption per unit GDP was verified to be the key obstacles for the further improvement of the performance level of rural community environment construction.Conclusion] In order to effectively improve the performance level of rural community environmental construction, we should further improve the diversified investment mechanism of community environmental construction, strengthen the treatment of rural domestic sewage, effectively improve the agricultural ecological environment, promote the reduction and efficiency increase of chemical fertilizers and pesticides, strengthen the pollution control of agricultural plastic films, comprehensively promote high-quality development, reasonably improve the utilization efficiency of energy and resources, effectively reduce the energy consumption per unit of GDP, and so on.
