SMEs(small and medium-sized enterprises) are the major component of China’s private economy, and are also an important force of China’s national economic development playing a huge role. There are plenty of SMEs in China, and they are the supporting objects of government in recent years as well as the following years, but they cannot get a further expansion during developing cause lack of funds. In the process of credit and financing, SMEs are short of collateral and conceal data deliberately, meanwhile the data are incomplete. This makes commercial have to bear a high credit cost. What’s more, the current systems of SMEs’ credit rating are all based on single enterprise, ignoring the hidden information and links that exist between associated enterprises. They cannot solve the problem about information asymmetry between commercial banks and SMEs. So, how can commercial banks use bank account system to build Bank-Enterprise network and find associated enterprises, grub credit information through associated enterprises, reduce credit cost, and build a set of SME credit rating system with more accurate and more effective is the key point as well as the main innovation of this paper.This paper is based on the theory of complex network and SMEs’credit rating. It tries to build bank-enterprise network to establish a new system of SMEs’ credit rating, combining with the inadequacies exciting in the process while commercial banks of China measuring the credit of SMEs.

On this basis, we are going to analyze the nature of SMEs based on the bank-enterprise network and propose implementation steps.After that, statistical characteristics of enterprise network will be given complexity analysis. The financial significance standing for these statistical characteristics of bank-enterprise network will also be revealed. Next, we’ll make a study of capital flow in network include its influence on credit rating and a study of enterprise relationship network about its meaning to guarantee system for SMEs. Build new credit rating indicators based on statistical characteristics and capital flow afterwards.
