京、津、沪、渝产业结构动态对比分析

A Dynamic Comparison on Industrial Structure of Beijing,Tianjin,Shanghai,and Chongqing

京、津、沪、渝4个直辖市经济发展存在差距,产业结构优劣是重要原因之一.采用产业结构信息熵定量分析了4个城市产业结构的动态变化,并进一步采用四分量偏离—份额分析法,评价了产业结构、竞争力及分配因素对4个直辖市经济增长的影响.结果显示:北京产业结构层次最高;上海第三产业优势未充分发挥;天津和重庆的第二产业优势突出,但天津产业结构演进活力不足,重庆产业发展缺乏特色且服务业发展滞后等.认为北京应走高端产业发展之路,上海要加强创新以提高现代服务业竞争力,天津应加强现代工业和现代服务业的发展,重庆要积极发展特色产业,推进制造业与服务业的深度融合.

There is a gap in the economic development among four municipalities-Beijing,Tianjin,Shanghai and Chongqing.One important reason is the strengths and weaknesses of their industrial structure.By means of industrial structure entropy,it has been analyzed in the paper that the dynamics differences in industrial structure in the four cities.Then,four-component share-shift model is used to evaluate the impact of industrial structure,competition power and distribution factors on economic growth of the four municipalities.The conclusion is that: Beijing's industrial structure is at the highest level;Shanghai's tertiary industry has not yet come into full play;Tianjin and Chongqing have great advantages in the second industry.However,the evolution of Tianjin's industrial structure is lack of the vitality,and the features of industrial development are inconspicuous and services industry lags behind in Chongqing.In the end,Beijing should pay attention to the development of High-end Industries;Shanghai should strengthen innovation to improve the competitiveness of the modern service industry;Tianjin should strengthen the development of modern industry and modern service industry;and Chongqing needs to develop locally-featured industries actively and promote the deep integration between manufacturing and service industries.
