Spatial Characteristics of Employment Density in Northeast China: Based on the Economic Census' s Data and Spatial Econometrics Analysis

基于区域密度方程和空间统计方法，利用两次经济普查的就业数据对东北地区就业密度的空间特征进行了研究。结果表明，东北地区形成了一个向右倾斜的倒“Y”字型就业密度格局，从北向南已经形成和正在形成的次中心逐渐增多，沿海化趋势和局域融合趋势也比较日月显，东北地区多中心就业格局已经形成。2004--2008年，东北地区整体就业密度的集中性还在继续加强，但不同局域就业中心表现出了不同的增长模式，黑龙江处于中心增长型扩散的单中心阶段，吉林省和辽宁省处于向心集聚和中心增长型扩散并存的多中心阶段，大部分就业中心均处于中心增长型扩散阶段，尚无去中心化扩散的就业中心。We make an analysis on the spatial characteristics of employment density in Northeast China based on the regional density equation and spatial statistical methods with economic census' s data. The results show that the employment centers concentrate along the coast, and the local convergence trend also become more and more obvious from northern to the southern part, the Multi-center pattern of employment has been formed in the northeast Regional, which is like an inverted letter "Y". From the year 2004 to year 2008, the concentration of the employment density in the northeast continues to strengthen, but different local employment centers showed a different pattern of growth. In the province level, Heilongjiang is in the stage of the spread through central growth based on a single center, Jilin and Liaoning province is in the stage of central agglomeration coexist with the spread through central growth based on the multi-center pattern of employment.基金项目:国家自然科学基金面上项目; 国土资源部2010年公益性行业科研专项经费项目中文核心期刊要目总览(PKU)中国科技核心期刊(ISTIC)中国社会科学引文索引(CSSCI)01014-203
