开发区集约利用途径SEM研究

The Study of Intensive Utilization Pathway in the Development Zone Based on SEM

本文以全国206个国家级开发区为样本,利用结构方程模型,从开发区集约利用评价指标体系内部结构入手,探索开发区集约利用途径。研究结果表明:(1)测量模型中只有土地有偿使用率、土地招牌挂率和高新技术产业用地率的标准因子荷载小于0.3,不能很好的解释对应的变量;(2)结构模型中土地开发程度与土地利用结构强度和土地利用效益之间的路径系数分别为0.85和0.70;管理强度与土地利用结构强度和土地利用效益之间的路径系数分别为0.40和0.49。在对以上研究结果分析的基础上得出以下结论:(1)开发区集约利用评价指标体系总体较好,仅有个别指标需要进一步优化;(2)开发区集约利用途径有两条:一是提高土地利用结构强度,二是提高土地利用效益,具体实现时都需从提高土地开发程度和提高土地管理强度两方面考虑,且目前的大多数开发区都是优先考虑提高土地开发利用程度,即优先考虑提高土地开发率、土地供应率和土地建成率。然后考虑提高土地管理强度,即提高到期项目用地处置率、闲置土地处置率、土地有偿使用率和土地招拍挂率;(3)这种发展模式不利于可持续发展,应该优先考虑提高土地管理强度,然后考虑提高土地开发利用程度,同时还应该拓宽土地开发利用的内涵。总而言之,提高开发区集约利用程度,应该双管齐下,走生态集约的可持续发展之路。

The aim of this study is to explore the better approach of land intensive utilization. Method of Structure Equation Model was employed. The results show that：（1）In Measurement model ,only the standard factor loading of land compensation utilization rate,the land signs hanging rate and land use rate of high-tech industries are less than 0.3,which is not good enough to explan for the corresponding variable. （2）In the structural modeLthe path coefficients between the degree of land development and the intensity of land use structure and land use efficiency is 0.85 and 0.70 respectively; the path coefficients between management intensity and the intensity of land use structure and land use efficiency is 0.40 and 0.49 respectively.It is concluded that： （1） The evaluation indicator system is overall reasonable, only individual indicator need to be optimized. （2）There are two ways to improve the level of intensive use in the development zone： The frist is to increase the intensity of land use structure ,the second is to improve the land use efficiency. To achieved it, the improvement of the degree of land development and intensity of land management should be considered,and give priority to the improvement of the degree of land development.. （3）However,this pattern of development is not conducive to sustainable development, priority should be given to improve land management strength, then consider raising the degree of land development and utilization. What＇s more, the connotation of land development and utilizationshould also broaden.Improving land management strength and the utilization degree of land development at the same time to achieve sustainable development of the eeo- intensive.
