摘要：本文首先运用动态最优化模型,在土地利用结构引起产业结构变化视角下,分析经济快速发展过程中土地城市化对生态环境质量的影响机理,得出以下结论:(1)当土地城市化率较低时,经济发展以粗放式发展模式为主,土地利用效率不高,工业生产过程对生态环境的破坏程度大,这使得地均土地生态环境质量下降;(2)当土地城市化率较高时,经济发展以集约式发展模式为主,国家在土地政策和产业政策上向服务业及高新技术产业等倾斜,同时出台环境规制政策控制环境污染程度,生产过程对土地生态环境质量的影响降低,这使得地均土地生态环境质量有所提高。土地城市化率和地均土地生态环境质量之间呈现U型曲线关系。随后,运用空间自适应半参数模型,对土地城市化率与地均土地生态环境质量之间的关系进行计量分析,验证了土地城市化率和地均土地生态环境质量之间呈现U型曲线关系的假说。样本数据显示东部地区基本上均位于U型曲线的右边,而中西部大部分地区位于U型曲线的左边。由此得出以下启示:(1)进一步完善环境规制政策;(2)实施建设用地减量化政策;(3)实施土地指标的跨区域交易。
Many empirical studies show a strong association between economic development and land urbanization.Land urbanization drives land use change and has altered the land use structure.The literature demonstrates that there is a negative relationship between land urbanization and ecological environment quality.However,it is not known whether land urbanization also improves environmental quality.In this paper,we answer this question theoretically and empirically.First,we analyze the mechanisms behind the impact of the land urbanization rate on environmental quality and how the impact changes across different stages of economic development in China.Then,we analyze the relationship between the land urbanization rate and environmental quality empirically using a spatially adaptive semi-parameter model and Chinese provincial panel data to verify the results of the theoretical analysis.Finally,we make policy suggestions based on the theoretical and empirical analyses.We construct a theoretical model to analyze the relationship between the land urbanization rate and environmental quality based on the dynamic optimization models of Turnbull(2004)and Litchberg&Ding(2009).We conclude that there is a U-shaped curve relationship between the land urbanization rate and environmental quality.Through the comprehensive use of land policy,environmental regulation policy,industrial policy,and fiscal and taxation policy,the government can make the relationship between land urbanization and the environment a positive one.Economic development is dominated by the extensive development model when the land urbanization rate is low.Whether local governments convert more farmland for industrial is affected by the economic development level,industrial structure,technical level and the GDP and tax assessment of the central government.The industrial production process causes great damage to the environment in this case.All of these factors reduce the environmental quality.Economic development is dominated by the intensive and economic development model when the land urbanization rate is high.Agricultural land is mainly used for tertiary and high-tech industries.The government strengthens environmental regulation policies to control the degree of environmental pollution,reducing the impact of production processes on the environment.The willingness of residents to pay for the environment increases as the income of residents increases.This means that the environmental quality starts to increase when the land urbanization rate is sufficiently high.Reverse causality and omitted variables lead to endogeneity between land urbanization and ecological environment quality.A spatially adaptive semi-parametric model is applied to avoid the endogeneity problems a parametric model would have and to overcome the curse of dimensionality in a non-parametric model.Our econometric analysis verifies the hypothesis that the relationship between the land urbanization rate and the environmental value per capita is a U-shaped curve.Sample data show that the eastern region of China is generally on the right side of the U-shaped curve,while the central and western regions are mostly on the left side of the U-shaped curve.The Chinese central government should strengthen its environmental regulation policies,land policies and other measures to adjust the industrial structure so that each province enters the stage where increasing land urbanization increases the environmental quality as soon as possible.Based on the theoretical and empirical analysis,we make the following policy suggestions.(1)The government should strengthen its environmental regulation policies to protect the environment.(2)The government should further implement the policy of reducing construction land;(3)The government should implement cross-regional transactions of land indicators to protect basic farmland and ecological spaces.
