新疆绿色发展效率及其时空模式特征

Regional Green Development Efficiency and Spatio-Temporal Evolution Model in Xinjiang

区域绿色发展效率的增长有助于协调资源有效配置与经济发展并带动绿色技术创新。文章利用遥感数据和相关社会经济数据建立新疆绿色增长指标体系,并通过超效率SBM模型与TOPSIS排序模型,对新疆各县市绿色发展效率时空分异特征及其演变过程进行分析,并使用重心转移与空间自相关性方法定量测度空间聚集规模与未来发展趋势。研究表明:(1)2000—2016年,新疆区域绿色发展程度存在较大空间异质性;(2)Ⅰ、Ⅱ与Ⅲ三个时期新疆各县市的绿色增长效率具有明显的空间正相关性且正相关性趋于增强;(3)2000—2016年,绿色增长效率的重心继续向东北方向迁移。研究结果对新疆丝绸之路经济核心区的生态文明建设和绿色发展提供科学支持。

The growth of regional green development efficiency contributes to the coordination of efficient resource allocation and economic development and drives green technology innovation.By using remote sensing data and relevant socio-economic data to establish the green growth index system in Xinjiang,we analyze the spatial and temporal variation characteristics of green development efficiency and its evolution process in each county and city in Xinjiang through the super-efficient SBM model and TOPSIS ranking model,and use the center of gravity shift and spatial autocorrelation methods to quantitatively measure the spatial aggregation scale and future development trend.The following results were obtained:(1)From 2000-2016,there was a large spatial heterogeneity in the degree of regional green development in Xinjiang;(2)The green growth efficiency of Xinjiang counties and cities in periodsⅠ,ⅡandⅢhad obvious positive spatial correlation and the positive correlation tended to increase;(3)From 2000-2016,the center of gravity of green growth efficiency continued to migrate toward the northeast.The results of the study provide scientific support for ecological civilization construction and green development in the core Silk Road economic region of Xinjiang.
