不同尺度城镇化水平特征差异性研究

Study on the Difference of Urbanization on Different Scales

本文以浙江省11个地市和69个县区为研究对象,采用统计分析法、GIS空间分析和地理探测器模型分析了2004~2014年间不同行政尺度下城镇化水平的差异性。研究结果表明:第一,市级和县级城镇化在时序上均具有明显的阶段特征,整体上市级城镇化高于县级;第二,市级和县级城镇化区域差异性均呈现每年减小趋势,市级区域差异性减少的幅度和速率比县级更快,2007年以前市级城镇化空间差异大于县级,从2007年开始县级城镇化空间差异大于市级;第三,从微观指标上看,市级和县级城镇化的主导指标相同,均为人均财政收入,人均社会消费品总额和人均GDP;从宏观城镇化子系统来看,市级的经济城镇化影响力最大,县级的人口城镇化影响力最大;第四,市级空间城镇化对城镇化主导子系统有较强的交互作用;而县级是经济城镇化。基于研究成果,地市级城镇化发展应关注经济水平,优化产业结构,完善交通空间条件;县区级城镇化发展应关注非农业人口比重以及人口就业类型,提升二三产业就业率。

Taking 11 cities and 69 counties of Zhejiang Province as the research object,using statistical analysis, GIS spatial analysis and geographic detector model analyze the difference of urbanization level un-der the different administrative scales in the study area from 2004 to 2014. Research shows：First,both citylevel and county-level urbanization has obvious characteristics in the time sequence, overall city-level ur-banization is higher than county-level;Second,the regional differences of city-level and country-level ur-banization show an annual decreasing trend, the magnitude and rate of the decrease of regional difference of city-level is faster than that of county-level,the city-level urbanization ＇s spatial difference is higher than that of county-level before 2007,the spatial difference of county-level urbanization is larger than that of city-level from 2007;Third,from the micro-indicators, the leading indicators of city-level urbanization and country level urbanization are per capita fiscal revenue, total per capita social consumer goods and per capita GDP; from the macro-urbanization sub-system, the city-level ＇s economic urbanization has the greatest influence,and the county-level＇s population urbanization has the greatest influence;Fourth,the city-level ＇s spatial urbanization has a strong interaction with the dominant subsystems of urbanization;while the countylevel is the economic urbanization. Based on the research results, the development of city-level urbanization should pay attention to Improving the economic level, optimizing the industrial structure, improving the traffic space conditions; county-level urbanization development should pay attention to the the proportion of non-agricultural population and the type of employment, improving the employment rate of secondary and ter-tiary industries.
