Abstract: This paper, based on China's land supply data from 2010 to 2018 gained from China Land Market website via Python program, uses spatial distribution center, regional Gini coefficient, cold-hot spot and panel data model to discuss the temporal-spatial evolution and mechanism industrial land supply in Yangtze river economic zone during bi-transitional periods of market and development and supply side reform, aiming at providing theoretical supports for optimizing industrial planning and promoting supply side reform. Supply of industrial land in Yangtze river economic zone shows a fluctuated decreasing trend with rising, falling and slowly increasing stages. Spatial distribution of industrial land citywide generally tends to be balanced with a shrinking regional land supply difference. Industrial land is the largest in the middle stream of Yangtze river with its distributing center migrating to Yangtze river delta. Land supply is influenced by industrial land price and economic level; it is promoted by increment of fixed asset investment, local financial income and gross industrial production.

Key words: industrial land, temporal-spatial pattern, mechanism, regional Gini coefficient, Yangtze river economic zone

摘要： 基于Python程序在中国土地市场网上抓取2010—2018年土地供应数据，运用空间分布重心、区位基尼系数、冷热点分析和面板数据模型，探讨市场和发展“双转型期”以及供给侧结构性改革下的长江经济带工业用地供应规模的时空特征及影响机理，以期为优化工业产业布局、推动供给侧结构性改革提供理论支撑。研究发现：长江经济带工业用地供应规模呈波动性减少的趋势，经历了先增后减又缓慢增加的阶段；市域工业用地空间分布总体趋向均衡，区域供地规模差异在缩小；长江中游地区工业用地供应规模最大，近年来空间分布重心向长三角地区移动明显；工业用地成交价格和经济发展水平对供应规模有显著影响，固定资产投资、地方财政收入以及工业总产值的增加都会促进工业用地供应规模的扩大。
