Research On Urban Land Use Efficiency In Northeast China

Land is the carrier of people’s survival and the foundation of social and economic activities.The development of cities cannot be separated from urban land.Land resources are scarce.As urbanization continuous to accelerate,the demand for land in cities is increasing,and the problem of "man-land contradiction" cannot be ignored.At the same time,affected by financial pressure and competition from other local governments,local governments have adopted Land fiscal behavior increases local fiscal revenue,leading to aggravation of resource misallocation and serious waste of land resources.Northeast China is rich in land resources,but it is in an important period of industrialization,urbanization and modern resource development.Northeast China is based on industrial development and has serious environmental pollution problems.At the same time,it faces the dual problems of land resource deterioration and ecological environment damage.Due to the dual pressure of the environment,to achieve the sustainable development of the city and the sustainable use of the land,we cannot sacrifice the environment.This study takes 34 prefecture-level cities in Northeast China as the research object,studies the urban land use efficiency from 2003 to 2019.First,the concept of urban land use efficiency is defined,clarify the influence mechanism of influencing factors;secondly,the static efficiency in Northeast China from 2003 to 2019 is measured through the SBM model,dynamic analysis is conducted through MalmquistLuenberger index,and the efficiency loss model is input-output analysis;then,combined with theoretical analysis,from the perspectives of social and economic development and government role,through Tobit regression model Conduct an empirical analysis on the influencing factors in Northeast China as a whole and resource-based cities;finally,draw the relevant conclusions,and put forward policy recommendations for this study.The main conclusions are as follows: From 2003 to 2019,the overall level of urban land use efficiency in Northeast China was relatively high,but the growth rate was slow,and there were differences in the level in various cities;the resource allocation level in Northeast China was relatively low,and pollution problems were relatively Seriously;for the Northeast region as a whole,the increase in economic development,the increase in population,the upgrade of structure and the increase in openness to the outside world have a significant positive effect in the Northeast region.The improvement of utilization efficiency has an inhibitory effect,but the effect is not significant.For resource-based cities,the reduction of population size has a significant effect of resource-based cities.The upgrading of industrial structure has an inhibitory effect in resource-based cities in Northeast China.The effect is not significant.In view of the problem in Northeast China,this study puts forward the following policy suggestions: focus on rationalising factor inputs,controlling land supply and reducing resource mismatch;revitalising stock and promoting intensive land use;strictly adhering to the bottom line of land concessions and establishing a sound regulatory mechanism;focusing on long-term development,adjusting the development direction of resource-based cities and promoting the efficiency of urban land use.
