High Structure Similarity in Manufacturing Sector may Threaten Industry Boom in Yangtze Delta Region

摘要

the author measured the same structure degree with the structure familiar coefficient and the division degree with the structure difference index of the manufacture industry in Yangtze delta in this article.Based on my analysis I got the special data about the negative relation between structure familiar and structure difference,at the same time,I got the exact data about the relation between structure coincide degree and structure difference degree,and defined a basic numerical value to judge the same structure degree.According to my analysis,I think the same structure degree of the manufacture industry is dropping and the division degree is rising in Yangtze delta area in recent years.
