The Relationship between Enterprise Performance and Heterogeneity and Homogeneity of Resource:A Case of Medicine Listed Corporation in China

There exists a sustainable preference difference between companies, but our study confirms that the difference may become smaller over time. Some authors think that the cause lies in the heterogeneity of resource, but it can not explain why the difference does not become bigger and bigger. So we think that there must exist some homogeneity resulted from the tradeablity and shareablity of the resource, and the standard of production, which causes the difference in preference and porfitebility between firms tend to become smaller.
