【摘要】：研究目的:分析城市群在城镇化进程中的规模特点,对其发展的适度性进行判断。研究方法:基于城镇规模边际成本和边际效益的基本理论,通过三次非线性回归方程建立城镇最佳规模分析模型和城镇发展规模适度性判断模型。研究结果:(1)在成本—收益视角下分析城镇的最佳规模,不能只看取得的经济效益高低或投入成本的大小,要通过城镇经济发展效益扣减成本投入后的盈利效率来判断;(2)城镇规模适度性分析模型在对实际规模与最佳规模的对比分析基础上,再通过城镇规模发展阶段和城镇规模增长趋势对其城镇规模适度性进行判断。研究结论:(1)应严格限制城镇规模大于500 km2的超大城市的发展;(2)应根据具体情况适度发展城镇用地规模在300—400 km2的大城市;(3)应当增强经济的拉动作用,促进城镇用地规模在200 km2以下的中小城镇的发展。
[Abstract]:Objective: to analyze the scale characteristics of urban agglomeration in the process of urbanization and to judge the appropriateness of its development. Research methods: based on the basic theory of marginal cost and marginal benefit of urban scale, the optimal scale analysis model and the appropriate judgment model of urban development scale are established by cubic nonlinear regression equation. The results are as follows: (1) to analyze the best scale of towns from the perspective of cost-benefit, we should not only look at the level of economic benefits obtained or the size of input costs, but also judge by the profit efficiency after deducting the cost input from the benefits of urban economic development; (2) on the basis of comparing and analyzing the actual scale and the optimum scale, the analysis model of the urban scale appropriateness is judged by the development stage of the urban scale and the trend of the urban scale growth. The conclusions of the study are as follows: (1) the development of megacities whose scale is larger than 500 km2 should be strictly restricted; (2) the large cities with the scale of 300-400 km2 should be developed appropriately according to the specific conditions. (3) it is necessary to promote the development of small and medium-sized towns with the scale of urban land less than 200 km2.
