Research On The Interactive Mechanism Between Urban Land Utilization And Economic Development

Land resources are the basis for economic development, urban land utilization is more closely associated with the economic development. For a long time China's extensive mode of economic growth resulted in the use of land resources, high-consumption, low output, a waste of huge resources. The rigidity constraint of the supply of urban land resource prompted us to find ways to improve land utilization, scientific and rational, economical and intensive land use, constructing a sustainable development path. As a result, comprehensively and profoundly depicts urban land use and economic development in the relationship between theory and reality have become an urgent need to address the problem.At present, researches on the the relationship between urban land utilization and economic development mostly are one-way single-factor studies, can not reflect well on the whole relationship between urban land utilization and economic development, and this may lead to land-use planning program can not adapt to and promote economic development, and even increase the "bucket effect" and bottlenecks of land in the economic development. But in fact, the relationship between urban land utilization and economic development is multi-factors two-way relationship. And this is the research space of this study.This article researches the interaction relationship and interaction mechanisms between urban land utilization and the various dimensions of economic development by integrating land economics, resource economics, urban economics, econometrics, industrial economics, systems theory and other disciplines relevant theory, with methods of systems analysis, combination of qualitative analysis and quantitative analysis, combination of theoretical research and empirical research and so on. Based on the analysis of urban land use and economic development-related theoretical research, appling the idea of systems theory, this article takes "land utilization-economic development" as a whole system, proposes the elements and theoretical analysis framework of a two-way interaction between urban land utilization and economic development. Appling the theory of gray canonical correlation analysis and simultaneous equation model, having quantitative research on the interactive mechanism of urban land utilization and economic development, from the aspects of theory, models and empirical research,take a comprehensive characterization of the impact of urban land dynamic change on economic development and the impact of economic development on urban construction land size and structure.The major research findings include:(1) Urban construction land area have a steady contribution to economic growth, and with the advances in technology, the extent of their intensive use have a gradual increase; at the same time, urban construction land area have a high degree of positive correlation with the second industry and tertiary industry output value of GDP, the proportion of the rate of industrialization and urbanization, the total area of urban construction land have close relationship with economic growth, industrial structure, industrialization and urbanization.(2) the use of gray canonical correlation analysis of urban land use structure and economic development, the intrinsic relationship between the various dimensions, studies show that:the rate of industrialization and per capita GDP and the proportion of tertiary industry GDP have a high degree of correlation with public facilities, land accounted for the proportion of urban construction land and industrial land account for the proportion of urban construction land. To reflect the correlation between urban land use structure and economic development, mainly through the industrialization of the relevance of the rate of per capita GDP, the tertiary industry output value of the proportion of GDP, and public facilities land proportion and the proportion of industrial land, therefore, when we want a industrial structure adjustment or land-use planning, we should focus on handling the relationship between them.(3) By constructing urban land use and economic development, simultaneous equation model, using national data study found that:urban construction land area have interactive relationship with economic growth, industrial structure, industrialization, urbanization. And economic growth, industrial structure, industrialization, urbanization and other aspects of economic development, urban construction land area both have a significant impact.(4) By constructing panel data-based urban land use and economic development, simultaneous equation model, using the country's eastern, central and western regions of the local data, research the local urban land use and economic development, the simultaneous nature of the differences, the study found:the eastern, central and western areas of urban land use are related to economic growth, industrial structure, industrialization, urbanization; while for the various dimensions of economic development, the urban construction land area have also significantly affected, which for urban land use and regional economic development decision-making.The theoretical value of this study is that, considering the interactive relationship between the various dimensions of urban land utilization and economic development, establishing of the relevant theoretical model, provide a scientific theoretical foundation for improving China's urban land utilization and economic development plan on the backgroud of the new land policyn; at the same time, having a very important practical significance for decision-making reference aim to raise the utilization rate of land, promote scientific and rational, economical and intensive land utilization, in order to strengthen the urban land utilization and economic development planning, take the road of sustainable economic development.The innovations of this article may include:(1) different from the one-way relationship analysis of urban land utilization and economic development of the existing literature, this article places land and the economic in the same system, research and analysis the two-way relationship of urban land utilization and economic development; (2) previous studies analysis the simple correlation between urban land utilization and economic development, but this article apply the theory of gray canonical correlation analysis analyzing a variety of urban land and economic development in the relationship between the various dimensions, that is the relationship between the nine categories of urban construction land such as residential land, public facilities land, industrial land, storage sites, external transport sites, roads and square land, municipal land for public facilities, green spaces and special land and economic growth, industrial structure, industrialization and urbanization; (3) previous studies establish one-way regression equation of urban land utiliazation and economic development, this article is different, under conditions of simultaneous nature of urban land utiliazation and economic development,using simultaneous equation model, on the one hand, establishes simultaneous equations model to have an empirical research on the interaction of China's urban land utiliazation and economic development, on the other hand, using the panel data that including cross-sectional data (all provinces) and time series data, by building simultaneous equation models based on panel data, analysis the simultaneous differences of urban land utilization and economic development in China's eastern, central and western regions.
