Along with the economic development and the acceleration of urbanization,urban construction land expands rapidly in China,and has resulted in a series of socio-economic problems.This article summarized the major points of controlling the unchecked and rash expansion of construction land in the academic circle,and analyzed the problems of regulating the expansion of construction land from three aspects.First,this article analyzed the relationships between socio-economic development and urbanization from the historical viewpoints,and pointed out that the expansion of construction land is a historical phenomenon which will be surely appeared in the development of human race.Second,the authors utilized two-sector model to analyze the importance of urbanization in the socio-economic development from the academic angles.At last,the authors utilize four-quadrant model and bidrent curve model to analyze the influence that brought by the strict control of construction land expansion.Through analysis,this article drew some conclusions.First,the expansion of construction land is a phenomenon which will surely appear in the social development.It is impossible to accomplish the national modernization on the basis of dualistic structure between urban and rural areas.Second,under the function of rent gradient gap,strict control of construction land expansion will not only obtain the anticipated effects,but also cause a series of socio-economic problems,such as land-levying contradiction,the appearance of limited property right house,and being dependant on lease instead of expropriation.Third,unreasonable policies and governmental behaviors are the roots of the unchecked and rash expansion of urban construction land.Based on these conclusions,this article proposed that three transformations should be realized to regulate the unchecked and rash expansion of construction land:transfers from quantity regulation to quality regulation,from direct regulation to indirect regulation,and from single-measure regulation to multi-measures regulation.
Along with the economic development and the acceleration of urbanization, urban construction land expands rapidly in China, and has resulted in a series of socio-economic problems. This article summarizes the major points of controlling the unchecked and rash expansion of construction land in the academic circle, and analyzed the problems of regulating the expansion of construction land from three aspects. First, this article analyzed the relationships between socio-economic development and urbanization from the historical viewpoints, and pointed out that the expansion of construction land is a historical phenomenon which Second, the authors utilized two-sector model to analyze the importance of urbanization in the socio-economic development from the academic angles. At last, the authors utilize four-quadrant model and bidrent curve model to analyze the influence that brought by the strict control of construction land expansion. Through ana lysis, this article drew some conclusions. First, the expansion of construction land is a phenomenon which will surely appear in the social development .It is impossible to accomplish the national modernization on the basis of dualistic structure between urban and rural areas .Second, under the function of rent gradient gap, strict control of construction land expansion will not only only obtain the anticipated effects, but also cause a series of socio-economic problems, such as land-levying contradiction, the appearance of limited property right house, and being dependant on the lease instead of expropriation.Third, unreasonable policies and governmental behaviors are the roots of the unchecked and rash expansion of urban construction land.Based on these conclusions, this article proposed that three transformations should be realized to regulate the unchecked and rash expansion of construction land: transfers from quantity regulation to quality regulation, from direct regulation to indirect regulation, and from single-measure regulation to multi-measures regulation.
