本文主要运用偏离-份额分析及其空间拓展模型对天津产业结构及竞争力水平进行了实证分析。结果表明,天津经济总量及各产业的增长中,竞争力因素比产业结构因素更能推动经济增长,第三产业与其他产业相比产业结构更优、竞争优势更强,但相对周边邻近地区,天津各产业并没有表现出产业结构优势。最后,结合天津三次产业比重变化指出了天津产业结构目前存在的问题,从产业结构高度化的角度提出了产业结构优化的建议。
This paper mainly uses the departure-share analysis and its spatial expansion model to make an empirical analysis of Tianjin’s industrial structure and competitiveness. The results show that in the total economic output and the growth of various industries in Tianjin, the competitiveness factor is more conducive to economic growth than the industrial structural factors. The tertiary industry has better industrial structure and competitive advantages than other industries. However, compared with other neighboring regions , Tianjin’s industries did not show the advantages of industrial structure. Finally, the paper points out the existing problems of Tianjin’s industrial structure in light of the changes in the proportion of the three industries in Tianjin, and puts forward suggestions on optimizing the industrial structure from the perspective of the industrial structure.
