城市群服务业集聚与经济增长——以长三角为例

【摘要】：基于长三角25个城市2001—2010年面板数据,本文对城市群服务业集聚与经济增长关系进行了实证分析,结果显示:长三角城市服务业集聚区位熵值大多在1.5以上,产业相对聚集且专业化程度较高,但区位熵值总体呈下降趋势;服务业集聚程度与区域经济增长呈现负相关关系,相应的弹性系数为-0.395,负效应影响明显,表明由集聚带来的该地区规模经济和专业化优势对经济增长的效应开始出现逆转,作为一种"经济信号"值得关注;模型控制变量,如生产性服务业市场规模、政府干预程度、人力资本水平和居民消费能力等均与经济增长均呈正相关。今后政府对服务业集聚的引导应注重从"量"到"质"的转变,注重对集聚多样化协调、集聚协同产业的发展以及集聚配套基础设施一体化的建设。
[Abstract]:Based on the panel data of 25 cities in Yangtze River Delta from 2001 to 2010, this paper makes an empirical analysis on the relationship between agglomeration of service industry and economic growth in urban agglomeration in Yangtze River Delta. The results show that the entropy value of agglomeration location of urban service industry in Yangtze River Delta is mostly above 1.5. The industry is relatively concentrated and the specialization degree is higher, but the entropy value of location shows a decreasing trend as a whole; There is a negative correlation between the degree of service industry agglomeration and regional economic growth, and the corresponding elastic coefficient is-0.395. the negative effect is obvious. It shows that the effect of economies of scale and specialization brought by agglomeration on economic growth begins to reverse, which is worth paying attention to as a kind of "economic signal". The model-controlled variables, such as the market size of producer services, the degree of government intervention, the level of human capital and the consumption capacity of residents, are all positively correlated with economic growth. In the future, the government should pay attention to the transformation from "quantity" to "quality", pay attention to the coordination of cluster diversification, the development of cluster synergy industry and the construction of integrated infrastructure of agglomeration.
