The...Urbanization is a complex process that covers a wide range of topics, of which population, industry and land urbanization are three important aspects. Jilin Province is an important agricultural province in China. The contradiction between population, industry and land urbanization is especially prominent here, and its coupling development is of great practical significance. In this paper, the coupling degree of population-industry-land urbanization in Jilin Province in 1990, 2000 and 2010 is measured by coupling mode. The spatial pattern of the coupling degree is analyzed by trend surface analysis and global and local spatial autocorrelation. The influence factors and their spatial differentiation are discussed using multiple linear regression(MLR) model and geographic weighted regression(GWR) model. The results show that: 1) the coupling degree of population-industry-land urbanization in Jilin Province is at a low level. Judging from the change of time scale, the urbanization of most research units is becoming more and more coordinated. From the comparison of spatial scales, there is significant spatial difference in the research units of different administrative levels. 2) Judging from the global change trend, the coupling degree of population-industry-land urbanization in the central region is higher than that in western and eastern regions. The coordination of urbanization in the central region is relatively good, and the distribution of the cold and hot spots is basically the same as that overall. 3) The spatial pattern of the coupling degree is related to the cold and hot spot distribution of the influence coefficient of urban population density and per capita urban construction land. The variation of the coupling degree spatial pattern is synchronous with the spatial change of the urban population density influence coefficient. 4) The degree of agglomeration of the urban population is the main factor promoting the coupling pattern of population-industry-land urbanization in Jilin Province, and the extent of its influence is gradually increasing. In addition, the level of city administrative, the efficiency of urban expansion and the capacity of market consumption also have an important influence on the coupling pattern.展开更多

The modes and trajectories of urban redevelopment have thus become areas of major concern for both policymakers and scholars. Taking the multi-actor participation nature of redevelopment, this paper stemming from the game-theoretical approach demonstrates in empirical terms on two major fronts. First, the redevelopment of industrial land without the transfer of land use right is shown to be deadlocked by the incapacitation of the original land-user and unlocked with the participation of the new developer. Second, the preference of the original land-user to maximize its interests by operating by itself rather than continue to cooperate with the new developer is observed in the post-redevelopment stage. Therein, the entrepreneurial local government acts only as a “mediator” between the two market entities and tends not to directly intervene in their cooperation. Thus that, it is the reasonable distribution of potential benefits or the pricing of different rights in the land property right bundle rather than their definition that matters more for land redevelopment. Because the delineation of land property rights has never been a problem in a mature land market, particularly for stock industrial land.展开更多

The degree of the low intensity of land use needs to be evaluated. The current method of comprehensive evaluation and grading by one index system has the limitations due to the existence of differences between regions and industries. This paper evaluates industrial land use intensity by Total Factor Productivity (TFP) analysis, which not only measures the intensity but also illustrates the ef-ficiency of input factors. This method is applied to the Beijing Economic-technological Development Area (BDA). A comparison analysis on factor use efficiency and input structure of capital and labor between industries is also carried out in the absence of a labor-income ratio.展开更多

This paper studied the interaction between land use changes and related transport routes, particular about how different transport routes and road nodes influence the conversion of industrial lands to residential and commercial uses respectively. Taking Changchun, an old industrial city in the rust belt of China as a case of study, we explored and compared the influences of different transport routes and road nodes on industrial land conversion. We found that surrounding the studied transport routes, more industrial lands were replaced by residential lands than by commercial lands. Also, apparent differences exist in the corridor effects of different transport routes(i.e., light rail, expressway and trunk road) and road nodes(i.e., expressway nodes and trunk road nodes) while the industrial lands convert to residential and commercial uses. Our research findings help us to illuminate the interactive relationships between transportation and industrial land conversion in old industrial cities which are undergoing social, economic and the related urban transition in Northeast China.展开更多

We did this by constructing an evaluation index system of intensive land use for industrial enterprises comprised of four sub-objective layers including land use structure, land use intensity, land input and land output, and nine element layers. We found that among 365 enterprises, 82 enterprises use land intensively, accounting for 22.47% of our sample; 215 enterprises use land moderately or have low use, accounting for 58.90% of our samples. Enterprises with intensive use tended to be metal smelting and rolling processing industries and communication equipment, computer and other electronic equipment manufacturing industries. Enterprises with moderate and low use tended to be from the special equipment manufacturing industry, pharmaceutical manufacturing industry and chemical raw materials and chemical industry. The potential area for enterprises with moderate and low land use is approximately 865.70 ha and accounts for 42.38% of total current land approved, indicating that their potentiality for intensive use is large.展开更多

Then, we analyze the dynamic changes in the urban industrial land's total factor productivity (UILTFP) by using the Malmquist productivity index approach, and we examine the UILTFP's conver- gence. The results show that the Pearl River Delta and the Yangtze River Delta have a higher UILUEs but show downward trends in UILTFPs. The other four zones, Beijing--rianjin-Hebei, Chengdu-Chongqing, Guanzhong-Tianshui and the Central Plains, show poorer UILUEs but have upward trends in UILTFPs. A significant excess supply of industrial land and labor exists in all six zones, and the zones in economically developed areas perform better in industrial output. The results of the convergence test do not support a-convergence but support condi- tional/3-convergence for all zones. These results indicate that the gaps in the UILTFP of in- dustrial land in all six zones, in fact, do not narrow, and the UILTFPs of cities will converge to their own steady states. The regression results of the influencing factors show that the ur- banization rate should be increased in the Pearl River Delta and reduced in Bei- jing-Tianjin-Hebei. The Yangtze River Delta and Chengdu-Chongqing should pay more atten- tion to the problem of industrial labor surplus, and the Pearl River Delta should reduce the proportion of industrial output. All zones should focus on improving the quality of the industrial economy and the land use intensity.展开更多

The expansions encroached upon a large amount of cropland, placing great challenges on national food security. Although the impacts of urban expansion on cropland have been intensively illustrated, few attentions have been paid to differentiating the effects of growing urban areas, rural settlements, and industrial/transportation land. To fill this gap and offer comprehensive implications on framing policies for cropland protection, this study investigates and compares the spatio-temporal patterns of cropland conversion to urban areas, rural settlements, and industrial/transportation land from 1987 to 2010, based on land use maps interpreted from remote sensing imagery. Five indicators were developed to analyze the impacts of built-up land expansion on cropland in China. We find that 42,822 km2 of cropland were converted into built-up land in China, accounting for 43.8% of total cropland loss during 1987-2010. Urban growth showed a greater impact on cropland loss than the expansion of rural settlements and the expansion of industrial/transportation land after 2000. The contribution of rural settlement expansion decreased; however, rural settlement saw the highest percentage of traditional cropland loss which is generally in high quality. The contribution of industrial/transportation land expansion increased dramatically and was mainly distributed in major food production regions. These changes were closely related to the economic restructuring, urban-rural transformation and government policies in China. Future cropland conservation should focus on not only finding a reasonable urbanization mode, but also solving the "hollowing village" problem and balancing the industrial transformations.展开更多

Although consensus has been reached on the evolutionary characteristics and spatial effects of industrial land, the influence mechanism of the evolution of industrial land on urban space still needs further exploration. Therefore, the evolution of industrial land in Xi’an from 2003 to 2019 is analyzed by the land use change matrixes, mixed degrees index, and sprawl index according to the multisource data. The results show that the scale change of industrial land is characterized by an inverted U-shaped curve and development zone-oriented spatial aggregation. Suburbanization, the conversion of agricultural land to industrial land in the suburbs, has intensified urban sprawl, resulting in more serious work-living imbalance and traffic congestion.Deindustrialization, the conversion of industrial land to residential, commercial, and business facilities land in the city center, has promoted urban sprawl, generated a large amount of construction waste, and caused a waste of resources. Based on the complex factors such as urban planning, land finance, and development zones, this study contributes to the research of the improvement of the rationality of urban land layout by revealing the influence mechanism of the evolution of industrial land on urban space.展开更多

The planning of industrial land for green belts has thus emerged as a way to help achieve these goals during Beijing's urban growth from morphological, social, and economic perspectives. First of all, this paper introduces the implementation mechanisms of the planning of industrial land for green belts, from which it abstracts a model of land adjustment and urban-rural cooperation. Secondly, the paper analyzes the effects and current dilemmas during the implementation of the planning of industrial land for green belts. Thirdly, results are compared with other spontaneously developed industries in the rural-urban fringe area to illustrate the changes brought about by the planning. Finally, the paper proposes three measures for future improvement, including balancing the industrial land use quotas between different townships, conducting cooperative land adjustment, and encouraging spontaneously developed industrial projects.展开更多

文摘Here, we used Bayes methods to evaluate land use intensity in 365 typical industrial enterprises across nine manufacturing industries in Hubei, China and calculated the potentiality of enterprises with moderate and low intensive land use. We did this by constructing an evaluation index system of intensive land use for industrial enterprises comprised of four sub-objective layers including land use structure, land use intensity, land input and land output, and nine element layers. We found that among 365 enterprises, 82 enterprises use land intensively, accounting for 22.47% of our sample; 215 enterprises use land moderately or have low use, accounting for 58.90% of our samples. Enterprises with intensive use tended to be metal smelting and rolling processing industries and communication equipment, computer and other electronic equipment manufacturing industries. Enterprises with moderate and low use tended to be from the special equipment manufacturing industry, pharmaceutical manufacturing industry and chemical raw materials and chemical industry. The potential area for enterprises with moderate and low land use is approximately 865.70 ha and accounts for 42.38% of total current land approved, indicating that their potentiality for intensive use is large.

文摘Based on an SBM model, this paper first analyzes the spatial differences of urban industrial land use efficiency (UILUE) in the six main economic zones of China. Then, we analyze the dynamic changes in the urban industrial land's total factor productivity (UILTFP) by using the Malmquist productivity index approach, and we examine the UILTFP's conver- gence. The results show that the Pearl River Delta and the Yangtze River Delta have a higher UILUEs but show downward trends in UILTFPs. The other four zones, Beijing--rianjin-Hebei, Chengdu-Chongqing, Guanzhong-Tianshui and the Central Plains, show poorer UILUEs but have upward trends in UILTFPs. A significant excess supply of industrial land and labor exists in all six zones, and the zones in economically developed areas perform better in industrial output. The results of the convergence test do not support a-convergence but support condi- tional/3-convergence for all zones. These results indicate that the gaps in the UILTFP of in- dustrial land in all six zones, in fact, do not narrow, and the UILTFPs of cities will converge to their own steady states. The regression results of the influencing factors show that the ur- banization rate should be increased in the Pearl River Delta and reduced in Bei- jing-Tianjin-Hebei. The Yangtze River Delta and Chengdu-Chongqing should pay more atten- tion to the problem of industrial labor surplus, and the Pearl River Delta should reduce the proportion of industrial output. All zones should focus on improving the quality of the industrial economy and the land use intensity.

文摘Over the past few decades, built-up land in China has increasingly expanded with rapid urbanization, industrialization and rural settlements construction. The expansions encroached upon a large amount of cropland, placing great challenges on national food security. Although the impacts of urban expansion on cropland have been intensively illustrated, few attentions have been paid to differentiating the effects of growing urban areas, rural settlements, and industrial/transportation land. To fill this gap and offer comprehensive implications on framing policies for cropland protection, this study investigates and compares the spatio-temporal patterns of cropland conversion to urban areas, rural settlements, and industrial/transportation land from 1987 to 2010, based on land use maps interpreted from remote sensing imagery. Five indicators were developed to analyze the impacts of built-up land expansion on cropland in China. We find that 42,822 km2 of cropland were converted into built-up land in China, accounting for 43.8% of total cropland loss during 1987-2010. Urban growth showed a greater impact on cropland loss than the expansion of rural settlements and the expansion of industrial/transportation land after 2000. The contribution of rural settlement expansion decreased; however, rural settlement saw the highest percentage of traditional cropland loss which is generally in high quality. The contribution of industrial/transportation land expansion increased dramatically and was mainly distributed in major food production regions. These changes were closely related to the economic restructuring, urban-rural transformation and government policies in China. Future cropland conservation should focus on not only finding a reasonable urbanization mode, but also solving the "hollowing village" problem and balancing the industrial transformations.

文摘As an organic part of urban functions, industrial land is of great significance to the urban healthy and sustainable development. Although consensus has been reached on the evolutionary characteristics and spatial effects of industrial land, the influence mechanism of the evolution of industrial land on urban space still needs further exploration. Therefore, the evolution of industrial land in Xi’an from 2003 to 2019 is analyzed by the land use change matrixes, mixed degrees index, and sprawl index according to the multisource data. The results show that the scale change of industrial land is characterized by an inverted U-shaped curve and development zone-oriented spatial aggregation. Suburbanization, the conversion of agricultural land to industrial land in the suburbs, has intensified urban sprawl, resulting in more serious work-living imbalance and traffic congestion.Deindustrialization, the conversion of industrial land to residential, commercial, and business facilities land in the city center, has promoted urban sprawl, generated a large amount of construction waste, and caused a waste of resources. Based on the complex factors such as urban planning, land finance, and development zones, this study contributes to the research of the improvement of the rationality of urban land layout by revealing the influence mechanism of the evolution of industrial land on urban space.

文摘In China there have been two models of stock land renewal:formal renewal and informal renewal,and there have been a wealth of studies on formal renewal.However,few studies have addressed informal renewal,as well as the governance logic behind the renewal model.Based on the analysis of policy documents,extensive interviews and a case study of Guangzhou,we explore the evolution,governance logic,consequence of renewal,and governance dilemmas of collectively owned industrial land renewal since 2000.Through redefining the land development rights of stock collectively owned land and reducing the transaction cost of land use change,informal renewal activities of collective industrial land have been legalized from top to bottom.Meanwhile,informal renewal meets local governments’demand for rural industrialization transition.The empirical study of Panyu District in Guangzhou shows that owing to lacking policy resilience,ineffective planning control,and village collectives’dependence on the rental economy,collective industrial land renewal results in frequent interest conflicts and continuation of transfer and lease,presenting a real estate-oriented feature.Therefore,the renewal policy should be innovated in terms of differentiated policy design,a balance of interests,and through improvement of the transfer and transaction mechanism,to strengthen informal renewal management.

文摘The regeneration of stock land has gradually occupied the mainstream of China’s urban development.In order to cope with the inherent complexity of land property rights and transaction costs in stock land regeneration,relevant urban policies need to play a necessary guiding role.Taking the downtown area of Tianjin as an example,this paper discusses the interaction between spatial regeneration and policy change of stock industrial land.Firstly,a spatial database is constructed through multi-party research to quantitatively describe the spatial and temporal evolution of the stock industrial land since 1995.Secondly,the relevant urban policies since 1979 are sorted out,and the characteristics of policy changes are evaluated and analyzed.Finally,through comparative studies,it is confirmed that the regeneration rate of stock industrial land is affected by policy change,and the speed of policy impact is subject to the policies’inherent characteristics,namely,"guiding policy"or"regulating policy."
文摘Beijing's green belt policy is three-fold:fi rstly to protect farmers' interests during urbanization, secondly to control the urban expansion, and thirdly to improve the ecological environment. The planning of industrial land for green belts has thus emerged as a way to help achieve these goals during Beijing's urban growth from morphological, social, and economic perspectives. First of all, this paper introduces the implementation mechanisms of the planning of industrial land for green belts, from which it abstracts a model of land adjustment and urban-rural cooperation. Secondly, the paper analyzes the effects and current dilemmas during the implementation of the planning of industrial land for green belts. Thirdly, results are compared with other spontaneously developed industries in the rural-urban fringe area to illustrate the changes brought about by the planning. Finally, the paper proposes three measures for future improvement, including balancing the industrial land use quotas between different townships, conducting cooperative land adjustment, and encouraging spontaneously developed industrial projects.

文摘Although China’s local governments are facing greater financial pressure,they often sell industrial land at low prices to attract investment.Local government land transfer strategies refl ect driving mechanisms of officials’behavior.Based on the micro data of about 340000 industrial land sales in 289 prefecture-level cities in China from 2006 to 2015,this paper divides industrial land transfer into two categories,namely land transfer with the aim of attracting investment and normal transfer,according to whether the transfer price is lower than the minimum price stipulated by central government.The paper explores the strategies of industrial land transfer under financial pressure and the motivation differences of officials with the help of changes in local land transfers after the introduction of economic stimulus policies.It is found that financial pressure will signifi cantly reduce local industrial land transfer with the aim of investment attraction.However,after the introduction of economic stimulus policies,although financial pressure has increased,the infl uence of financial pressure on local governments’investment-induced land transfer behavior significantly weakened due to the increase of out-of-system financing channels,thus industrial land transfer with the aim of attracting investment has increased signifi cantly.From the perspective of promotion incentives of officials,officials with longer term were more inclined to sell industrial land to attract investment.Therefore,it is necessary to rationally arrange the financial resources and powers of central and local governments,to adapt reasonable macro control method and strategy,and to build an offi cial evaluation system that meets the needs of high-quality development.
