Abstract: A quantitative evaluation method for evaluation of construction of ecological industrial park(EIP) was introduced.It was based on calculations of degree of the correlation between factories or enterprises in the park and recycling rate of their byproducts and wastes.The Yangzhou EIP was chosen as a case of study for evaluation using the method,and for comparison with some other industrial parks at home and abroad.It was found that the park lagged somewhat behind.Directions and approaches were recommended for further improving the ecological level of the Yangzhou EIP.And this method was found to be simple,sensitive and workable. 

Key words: ecological industrial park(EIP), evaluation method, degree of correlation, recycling rate of byproduct and waste
