摘 要 本文运用脱钩理论构建脱钩模型分析湖南省建设用地扩张与经济增长的协调关系及其空间差异，探索2011-2016年湖南省建设用地扩张与经济增长变化的脱钩特点。研究结果表明2011-2016年湖南省及各市州建设用地扩张与经济发展的脱钩指数波动较大，脱钩指数曲线呈“W”型变化；湖南省建设用地扩张与经济发展的脱钩类型以强脱钩为主，反映了湖南省经济发展逐渐由外延式向内涵式转变，经济发展的“稳增长、调结构”特征成效渐显；各市州建设用地扩张与经济发展的脱钩类型存在明显差异，强脱钩类型大致呈“一极两轴”式分布于长株潭增长极区域和京广、沪昆两个交通走廊带。

Abstract： This paper uses decoupling theory to constructs decoupling model to analyze the relationship and spatial differences between construction land expansion and economic growth in Hunan Province； meanwhile， the paper explores the characteristics of decoupling between construction land expansion and economic development changes in Hunan from 2011 to 2016. The results show that the decoupling index of construction land expansion and economic development in Hunan and its cities fluctuates greatly from 2011 to 2016， and the decoupling index curve changes in "W" shape. The main type of decoupling between construction land expansion and economic development is strong decoupling in Hunan， which reflects the gradual transformation of Hunan's economic development from extension to connotation， and the effect of "steady growth and structural adjustment" of economic development is gradually evident. There are obvious differences in the types in decoupling between the expansion of construction land and economic development in each city， and the strong decoupling type is roughly "one pole two axis" type distributed in Changsha-Zhuzhou-Xiangtan growth pole region and the traffic corridor belt of Beijing-Guangzhou and Shanghai-Kunming.

土地是人类生存、繁衍、社会经济活动的载体，是制约经济增长的关键因素，是支撑区域经济发展不可或缺的自然资源，是产业发展必不可少的条件。建设用地扩展成为国内外学者广泛关注的焦点[1-3]。当前我国普遍存在建设用地扩张过快，部分区域出现与经济增长不协调，土地利用方式粗放等现象。作为生产要素的土地与资本、劳动力、技术、管理等其它生产要素一道助推经济发展，如何解析土地要素与经济增长两者之间内在联系与作用机制，定量分析建设用地扩张面积与GDP增长率的关系，将脱钩理论运用到建设用地扩张与经济增长关系的研……
