在柯布-道格拉斯生产函数模型的基础上,借鉴罗默尾效模型的推导过程,对山东省经济发展过程中的资源环境尾效进行推导计算,结果表明由于资源环境的约束作用,1985-2012年山东省每年的城镇化进程降低20.46%,其中最主要的制约因素是环境污染和水资源的短缺.从山东省内部来看,资源环境的约束作用大体呈东低西高的格局,与城镇化率东高西低的格局相对应.因此,需要改变原有的发展方式,调整产业格局,减小资源环境的尾效,实现区域可持续发展.
The growth drag modeling Romer drawed from Cobb-Douglas production function model was used to calculate the growth drag of resource and environment in the process of economic development of Shandong prov-ince.The results show that the annual urbanization reduces 20.46%due to the role of resource and environmental constraints in 1985-2012, and the most important constraint is pollution and the shortage of water.It can be seen from the results that the constraints of resource and environment are low in the east and high in the west generally inside Shandong province, corresponding to the rate of urbanization.To achieve economic development and urbani-zation process, it is necessary to change the original mode of development, resources and the environment to reduce the growth drag and achieve regional sustainable development.
