The Performance Study Of Merged Listed Companies In Our Country

M&A is a very important problem in company performance for many scholars in different countries. For many years, lots of scholars have studied the problem deeply, in different views using different methods, in different views using same methods, in same views using same methods. However, conclusions about the same problem are different, even if using same methods or different methods from different scholars .Why? I think methods to study performance of M&A are feasible and mature. This situation has been proved by many facts. But, during dealing with samples, different scholars have their own standards. This makes the conclusions be not the same one. Besides, lots of papers have problems of careless sample classifying, and this does harm to our analysis of complex structure of shareholder-rights in our country. Based on the two factors, my paper gives some empirical studies to merged companies, and studies the performances from different exchange roads of shareholder-rights.
