摘要
【目的】本文旨在剖析既有城镇建设用地配置策略在人口收缩背景下的适宜性,通过分析城镇建设用地配置对社会经济发展的影响,为东北三省建设用地配置优化提供理论依据。【方法】以东北三省地级市为研究对象,以2010—2020年为研究期,在分析人口收缩与建设用地配置现状的基础之上,借助柯布-道格拉斯生产函数与面板数据模型等方法,探究建设用地规模投入与结构配置对社会经济发展的影响,并提出人口收缩背景下城镇建设用地发展所面临的挑战与优化策略。【结果】①人口收缩背景下城镇建设用地投入对社会经济增长具有抑制作用,“以地谋发展”式的用地投入模式面临失效;②居住用地、公共管理与公共服务用地投入对社会经济增长具有抑制作用,工业用地投入具有促进作用但已边际报酬递减,着重供给此3类用地的传统用地结构配置策略适宜性下降。【结论】收缩城市面临城镇建设用地“超配”和“错配”的风险,应以控制用地规模、协调人地关系为前提,积极调整用地结构、优化资源配置,从而实现建设用地高效发展,促进社会经济发展。
[Objective]This study aimed to analyze the suitability of existing urban construction land allocation strategies in the context of population decline.By examining the impact of urban construction land allocation on socioeconomic development,it provides a theoretical basis for optimizing construction land allocation in the three provinces of Northeast China.[Methods]This study focused on the prefecture-level cities in Northeast China and took 2010—2020 as the research period.Based on the analysis of the current situation of population shrinkage and construction land allocation,we used the Cobb-Douglas production function and panel data models to explore the impact of the scale and structure of construction land on socioeconomic development.Additionally,we identified the challenges and optimization strategies for urban construction land development under the background of population shrinkage.[Results](1)Under the background of population shrinkage,the planned expansion of urban construction land has a inhibitory effect on socioeconomic growth,and the“land input-oriented development”model is facing ineffectiveness;(2)The input of residential land and public management and service land has a inhibitory effect on socioeconomic growth,the input of industrial land has a promoting effect but with decreasing marginal benefits.The suitability of traditional land allocation strategies emphasizing the supply of these three types of land has decreased.[Conclusion]Shrinking cities face the risks of“over-allocation”and“misallocation”of urban construction land.To address this,it is essential to control the scale of construction land,harmonize the relationship between population and construction land scale,and actively adjust the land use structure and optimize resource allocation.These measures will improve the efficiency of construction land and promote socioeconomic development.
