长江经济带工业用地市场化水平的时空格局演变及驱动因素研究

Study on Temporal and Spatial Pattern Evolution and Driving Factors of Market Level of Industrial Land in Yangtze River Economic Belt

工业用地市场是推动长江经济带要素市场化配置改革的关键载体,而准确量化工业用地市场化水平是促进该区域要素合理流动、构筑高质量发展国土空间布局的客观需要。运用GIS空间分析和Dagum基尼系数法系统考察2007~2018年长江经济带工业用地市场化水平的时空格局演变特征,并采用空间杜宾模型(SDM)揭示工业用地市场化水平的主要影响因素。结果表明:(1)研究时期内长江经济带工业用地市场化水平整体上提升,但存在一定的区域差异,具体表现为下游地区>上游地区>中游地区;(2)超变密度是长江经济带工业用地市场化水平差距的主要来源;(3)长江经济带工业用地市场化水平存在正向的空间互动效应,其中财政约束、地方政府间竞争、经济发展水平、产业结构和固定资产投资是影响工业用地市场化水平的主要因素。

The industrial land market is the key carrier to promoting the market-oriented allocation reform of the elements in the Yangtze River Economic Belt,and the accurately quantity of the market-oriented level of the chemical industry land is the objective need to promote the rational flow of the elements in the region and to build a high-quality development of the land and space layout.Using GIS spatial analysis and Dagum Gini coefficient method to systematically investigate the evolution characteristics of the spatial and temporal pattern of industrial land marketization level in the Yangtze River Economic Belt from 2007 to 2018,and using the spatial Dubin model(SDM) to reveal the main influencing factors of industrial land marketization level.The results show that:(1) The marketization level of industrial land in the Yangtze River Economic Belt has been improved as a whole during the research period,but there are some regional differences,which are manifested in the downstream>upstream>middle reaches.(2) Hyper-variable density is the main source of the market-oriented level gap of industrial land in the Yangtze River Economic Belt.(3) There is a positive spatial interaction effect in the marketization level of industrial land in the Yangtze River Economic Belt,in which financial constraints,competition among local governments,level of economic development,industrial structure and investment in fixed assets are the main factors affecting the marketization level of industrial land.
