【摘要】：基于2005~2014年地级及以上城市市辖区数据,定量分析了中国280个市辖区范围的城市经济效率时空演变特征,并探讨城市经济效率的影响因素。结果表明:城市经济效率得分不高,变化幅度不大;城市规模效益梯度比较明显;城市经济效率与城市行政级别格局一致;区域差异较小并且呈现缩小趋势,省内差异贡献明显大于省间差异贡献;城市经济效率的空间格局比较稳定,形成了辽中南、京津冀、山东半岛、长三角、珠三角等"群"状分布高值区域,以群内核心城市为中心,与群内较高、中等城市经济效率城市共同组成"核心—边缘"空间格局,而低水平城市则成片分布于中部和西部地区;所选6个因素对城市经济效率均有正向影响,其中城市规模、投资强度、区域联系的影响程度居前3位;地理区位差异是客观因素,要素禀赋是初始因素,而投资强度、区域创新投入等是直接因素。
[Abstract]:Based on the data of prefecture-level and above urban districts from 2005 to 2014, the temporal and spatial evolution characteristics of urban economic efficiency in 280 municipal districts in China are quantitatively analyzed. The results show that the score of urban economic efficiency is not high and the range of change is not high; The gradient of urban scale benefit is obvious; The pattern of urban economic efficiency is consistent with that of urban administrative level; The regional difference is smaller and the trend is smaller, the contribution of the difference within the province is obviously larger than that of the difference between the provinces. The spatial pattern of urban economic efficiency is relatively stable, forming high-value "group" distribution areas, such as central and southern Liaoning, Beijing-Tianjin-Hebei, Shandong Peninsula, Yangtze River Delta and Pearl River Delta, with the core cities as the center and higher in the group. The economic efficiency cities in the middle cities form the "core-edge" spatial pattern, while the low level cities are distributed in the central and western regions. The selected six factors have positive influence on the urban economic efficiency, among which the scale of city, the intensity of investment and the degree of regional connection are among the top three. Geographical location difference is an objective factor, factor endowment is the initial factor, and investment intensity and regional innovation investment are direct factors.
