Two indexes,modified Krugman index(MKI_(ij))and structural superposition index(SSI_(ij)),that can measure to the structural superposition of manufacturing were put forward based on interrelated study.Their equivalence were proved.Meanings of similar coefficient of structure(S_(ij))and structural superposition index(SSI_(ij))were analyzed.It is shows that SSI_(ij) was more appropriate than S_(ij) to measure the degree of same structure of manufacturing.The degree of same structure of manufacturing in delta area of Changjiang river were measured by using the S_(ij) and SSI_(ij).The results indicated that the degree of similarity was bigger than the degree of superposition and their differences were remarkable.whereas,the results of measurement to the structural convergence by using the S_(ij) and SSI_(ij) were same.
