关键词:建设用地;供给结构;一般均衡模型;门限回归;山东省 Abstract In order to reflect the impact of local government land supply behavior on migration, clarify the mechanism of population inflow influenced by construction land supply structure adjustment. Here,we built a general equilibrium model for local government,enterprise and residents using panel data for prefecture-level cities in Shandong,China from 2001-2013. We analyzed the empirical impact of construction land supply structure of local governments on population inflow using threshold regression. We found that the construction land supply structure has an inverted U type relationship with population inflow. The effects on population inflow are different when construction land supply structures are different. The (0,0.823) interval enhances the value of the construction land supply structure and helps draw population inflow while increasing the proportion of industrial land or decreasing the proportion of commercial and residential land. The (0.823,∞) interval has a negative impact on population inflow if we continue to increase the proportion of industrial land or reduce the proportion of commercial and residential land. The partial regression coefficients of construction land supply structure is less than the population size (26.617 3)and city location (11.445 5)and greater than infrastructure investment (1.399 5). This indicates that the structure of construction land supply is an indispensable factor to population inflow. Based on real demand of the government itself on population inflow,local governments can use the construction land supply structure as a tool and adopt different ways to regulate and guide the population inflow and outflow.

在数值模拟过程中,设其他影响因素外生给定,通过调整建设用地供给结构的数值来反映居民效用的变化趋势。数值模拟中各系数取值如表1所示。 根据表1中的参数设定,将建设用地供给结构作(Si)为自变量,将居民效用作(Ui)为因变量,采用公式(20)进行数值模拟,结果如图2所示。从图2中可以看出,在控制其他影响因素的情况下,随着建设用地供给结构(Si)的变化,居民效用(Ui)呈现出明显的倒U型变化趋势。由于效用水平是人口流动的决定因素,根据公式(20),可以得出如下一个可检验的研究假设:人口流动由城市的区位(k1)、环境和气候(k2)、基础设施投资水平(Ui)、建设用地总规模 人口规模(Ni)、建设用地供给结构决定(Si),在控制其他影响因素的情况下,建设用地供给结构存在一个最优值 ,对应着居民效用的最大化水平(Ui),其将建设用地供给结构(Si)划分为 两个区间;在区间 内,在建设用地供给结构中增加工业用地比重或降低商住用地比重,有助于提升居民的效用水平,进而吸引人口流入;在区间 内,在建设用地供给结构中增加商住用地比重或降低工业用地比重,有助于提升居民的效用水平,进而吸引人口流入。 Table 1 表1 表1参数取值 Table 1The values of model parameters

本文通过模型推导和实证研究发现: (1)建设用地供给结构处于不同区间时,其变化对居民效用的影响方式存在明显差异。 (2)建设用地供给结构对人口流入的影响小于人口规模和城市区位,但是大于基础设施投资水平,其对人口流入具有较为重要的影响。 针对建设用地供给结构对人口流入所具有的较为重要的影响及其倒U型的特殊影响方式,认为地方政府可以利用建设用地供给结构作为工具,根据自身对人口流入的实际需求采取差别性的调控方式,具体思路如图3所示。 显示原图|下载原图ZIP|生成PPT 图3建设用地供给结构分类调控方式 -->Figure 3The methods of classification regulation of construction land supply structure -->
图3中,在纵、横轴交点(L*、S*),劳动市场达到均衡,建设用地结构处于倒U型曲线的拐点,按照劳动力市场供求状态和建设用地结构所处区间产生4种情景分类。具体而言,对于劳动力市场供小于求,人口规模未超过城市承载能力,需要人口流入的地区,如果其建设用地供给结构处于(0,]区间,可以考虑增加工业用地比重或降低商住用地比重;如果其建设用地供给结构处于(,+∞)区间,可以考虑增加商住用地比重或降低工业用地比重,从而提升居民的效用水平,吸引人口流入。反之,对于劳动力市场供大于求或人口规模超过城市承载能力,需要人口流出的地区,如果其建设用地供给结构处于(0,]区间,可以考虑增加商住用地比重或降低工业用地比重;如果其建设用地供给结构处于(,+∞)区间,可以考虑增加工业用地比重或降低商住用地比重,从而降低居民的效用水平,引导人口流出。 The authors have declared that no competing interests exist.
