Abstract：The National 14th Five-Year Plan clearly proposes to speed up the modernization of the industry chain.It is an important theoretical and practical problem that deploying the innovation chain,financial chain and policy chain around industry chain and promoting the integration development of innovation chain,industry chain,financial chain and policy chain (or four chains for short).Based on the theory of regional economy,this article analyzes the theoretical mechanism of the ‘four chains’integration,and builds the integration evaluation index system of ‘four chains’,consisting of 4 primary indicators and 12 secondary indicators.Taking the data of 21 prefecture-level cities in Guangdong Province in 2017 as an example,this article uses the principal component analysis method to evaluate integration development of ‘four-chains’of various prefecture-level cities in Guangdong province,and classify each city by the systematic cluster analysis method.The results show that the Pearl River Delta region is at a high level of ‘four chains’integration development,Guangzhou is the highest,Shenzhen and Dongguan are the second,Huizhou and Zhaoqing are the lowest.The integration development of ‘four chains’in other regions is at a relatively low level ,but the difference between these regions is insignificant,and the integration development of each region is relatively consistent.
