本文以长三角两省一市1985－2010年生产者服务业和制造业增加值为依据，对二者的互动关系进行了实证分析，结果表明不仅生产者服务业整体上对制造业具有支撑作用，而且生产者服务业内部各个行业也与制造业相互影响，但由于发展水平和行业特性不同，影响程度又有差异。并据此提出了促进长三角地区生产者服务业与制造业互动发展的对策建议。

英文摘要：

This paper empirically analyzes manufacturing of Yangtze River Delta, based on the interaction between producer service industry and the added values of them from 1985 -2009 of Jiangsu province, Zhejiang province and Shanghai. The results show that the producer service industry supports the development of manufacturing as a whole. Moreover, each producer service industry and the manufacturing also influence mutually. But due to their different developing levels and characteristics, the influence of each producer service industry on manufacturing is also different. According to the empirical results, we propose the countermeasures for the interaction of the producer service industry and manufacturing of Yangtze River Delta.
