Study On Land Use Efficiency Of Jilin Province In The Process Of Urbanization

With the rapid development of the urban economy and the expansion of the space for human activities,the constraints on the total amount of land resources have become more and more obvious.Therefore,the characteristics of production factors of land resources in the economic system are also more prominent.The development of urbanization in my country is limited by the fact that the total population is large,but the per capital land is insufficient.Intensive use of land is an inevitable choice for the development of urbanization in China.The characteristics of production factors of land resources and the nature of state-owned property rights mean that the allocation of land resources has a significant macro-control function in China.As an important northeast industrial base in China,Jilin Province started early in urbanization development and grew rapidly.But in recent years it has experienced slower growth and low quality problems.Particularly,the extensive economic growth mode has caused great damage to the ecological environment,affecting the production and life of cities in the Northeast region,and damaging the public health of residents.Therefore,from the perspective of land use efficiency,this dissertation systematically studies the economic mechanism,output efficiency,utilization efficiency and influencing factors of land resource use in the process of urbanization in Jilin Province.It is expected to provide the necessary efficiency decision-making perspective for the optimal allocation of land resources,so as to explore a new guiding direction of macro-control policies for the structural optimization adjustment and intensive growth path transformation of economic development in Jilin Province.Land has different definitions in different disciplines.This article focuses more on the concept of land resources,highlighting the availability and scarcity of land on the earth's surface.Intensive land use pays more attention to its rational use and allocation within and between economic,social and ecological systems.The land use efficiency naturally focuses on the effective display of its economic benefits,and its connotation lies in the contrast between the actual benefits of land resource utilization and the optimal benefits.The improvement of land use efficiency depends on the production technology conditions and the reasonable allocation of other input factors.The land intensive use mechanism in the development of urbanization is that non-agricultural land,especially urban construction land,can promote the rapid accumulation of production factors in space.The gathering of the elements of urbanization has brought about the rapid development of the urbanization economy,and the main supporting force is that the intensive use of urban construction land and the sharing of urban infrastructure have made the external spillover effects of the agglomeration economy fully developed and released.In recent years,the urbanization development speed of Jilin Province has been relatively slower and lower than the national average level.The urbanization development of Jilin Province mainly has three problems: lagging industrial structure adjustment,excessive expansion of land scale,and low efficiency of land intensification.All of these problems are related to the input and utilization of land resources.This dissertation uses the comprehensive evaluation method of multi-dimensional factors to calculate and evaluate the intensification level of urban land use in Jilin Province.The results show that most urban land intensification levels are increasing,but the gap between cities is very significant.It is mainly embodied in three aspects: utilization intensity,utilization structure and utilization efficiency.Using the time series econometric model,we have initially explored the long-term coordinated relationship between urbanization and land use efficiency,and found that population urbanization is the long-term Granger reason for the increase in land use efficiency.In the short term,population urbanization may lead to fluctuations in land use efficiency,but there is a correction mechanism between the two to promote their adjustment to a long-term coordinated state.The efficiency of agricultural land use in Jilin Province is at a low level in the country,and the efficiency difference between cities in the Jilin Province is very significant.In rural areas around cities with abundant cultivated land resources,the efficiency of agricultural land is often not high.The calculation results based on interprovincial panel data show that the agricultural land use efficiency of Jilin Province in most years is significantly lower than the national average.,There are also problems of backward production technology and unreasonable factor structure allocation.This also makes the land use efficiency of agricultural production in Jilin Province significantly lower than its technical efficiency level.The calculation results of the super-efficiency CCR model based on the province's urban panel data show that most cities in Jilin Province with higher agricultural land use efficiency are located in the eastern region,while the central and western cities with relatively abundant arable land resources have low agricultural land use efficiency.Even the utilization efficiency of some cities is much lower than that of the eastern region.The efficiency of agricultural land use in Jilin Province is affected by its own production conditions and the agglomeration of urbanization industries.The efficiency of urban construction land in Jilin Province is at a relatively low level in the country and shows an inverted N-shaped change in time series.The efficiency difference between cities in the province is very significant,and the performance of prefecture-level cities with large populations is not outstanding.The calculation of the super-efficiency model based on the national technology reference set shows that the efficiency of urban construction land in Jilin Province declined in the early stage of the northeast revitalization and rebounded in the mid-term,but after 2010 it turned to a downward path.The difference in construction land efficiency among cities in Jilin Province is very significant.Large-scale prefecture-level cities do not perform well in land use efficiency.Only 3 of the 8 prefecture-level cities have an average annual utilization efficiency greater than 0.5.Other prefecture-level cities' efficiency is at a low level.In the time series,the construction land efficiency of most cities is in a trend of declining fluctuations,and unreasonable element structure configuration is widespread.This has also made the decline in construction land efficiency in most cities greater than technical efficiency.The extensive expansion of construction land without the followup of capital and other factors input has made land use efficiency continue to decline.The continuous decline in the efficiency of construction land in most cities in Jilin Province is mainly due to the year-by-year expansion of technical efficiency losses.On this basis,structural inefficiency has exacerbated the further deterioration of its efficiency level.Promoting the progress of production technology in invalid cities is the focus of improving the efficiency of construction land.The test results using the urban panel data of Jilin Province show that the increase in the intensity of unit land investment can significantly promote the efficiency of urban construction land,but it is restricted by the scale of construction land per capital.Only when the scale of per capital construction land is below a certain critical value will it be effective to increase the investment intensity.And the expansion of per capital construction land will result in a continuous loss of land use efficiency.The per capital urban road area has a significant positive effect on land use efficiency,but the impact of per capital public financial expenditure shows a reverse restriction mechanism.This reflects the irrationality of the structure of public service fiscal expenditures.The scale effect of urban population in Jilin Province presents an non-obvious inverted U-shaped characteristic,which is closely related to the low level of population agglomeration in most cities.The impact of the industrial linkage structure on the efficiency of urban construction land shows a positive U-shaped characteristic.The development of the tertiary industry in most cities generally lags behind,and there is still a large gap between the average threshold and the critical point.It is still difficult to promote industrial diversification and promote the intensive and efficient use of land.The efficiency loss caused by the unreasonable construction land structure is widespread in the cities of Jilin Province.An excessively high proportion of residential land will lead to a continuous efficiency loss of construction land.The sample data estimation results show the fact that the supply of residential land in most cities is too fast.The analysis of the heterogeneity of spatial characteristics shows that the central and western regions of Jilin Province,which are rich in agricultural land resources,are restricted by the level of economy and urbanization,and the impact of infrastructure,machinery utilization intensity and urbanization development level on the efficiency of agricultural land use is less than that of the central and eastern regions.Only nontechnical fertilizer use intensity has a greater impact than the central and eastern regions.Among the influencing factors of construction land utilization efficiency,the overall decline area is mainly urban expansion,and the investment intensity and unit fiscal expenditure are the most significant.However,the proportion of residential land and the proportion of industrial land have the most significant promotion effects.Finally,based on the problems of the province's land resource utilization efficiency,from the theoretical mechanism and the empirical relationship revealed by the measurement model,from the three major aspects of agricultural land efficiency optimization,urban construction land efficiency optimization,and urbanization development pattern.The implementation of the three main strategies of rural revitalization,new-type urbanization and the comprehensive revitalization and development of the Northeast gave policy recommendations.Specifically,it includes advancing the advancement of agricultural production technology,advancing agricultural mechanization and modernization,advancing the construction of urbanrural integration,accelerating the reform of agricultural land ownership,strictly implementing the total and incremental control of construction land,rationally optimizing the allocation structure of factors,and promoting the reform of the household registration system.etc.
