Study on Land Use Efficiency and Influencing Factors in Huaihai Economic Zone
The study of land use efficiency is helpful to improve the efficiency of land resource allocation and sustainable development . Based on the input and output data of land elements in 10 prefecture-level cities in Huaihai Economic Zone,the data envelopment model is used to quantitatively evaluate the land use efficiency. The results show that the land use efficiency of Huaihai Economic Zone is rising in fluctuation,showing different development trends in time,and the cities with higher land use efficiency in space show a trend of distribution along the regional development axis. Input redundancy and excessive output have a negative impact on land use efficiency;the number of industrial enterprises above designated size,the level of industrialization,the degree of government intervention and GDP have a positive impact on land use efficiency,while the level of fixed asset investment and pollution have a negative impact. It is recommended to improve land use efficiency through four aspects:industrial coordinated development,environmental regulation,reduction of land element redundancy and classification guidance.
