The performance loss analysis of foreign capital M&A

The article holds the opinion that cross-border mergers and acquisitions (short for "M&A") may lead to production concentration and monopoly in a lager range. Monopoly could bring the waste of social resource and the loss of social welfare and social efficiency. The article analyses a series of products produced by M&A with the Williamson Heuristic Model. And it finds M&A arouses industrial concentration, impels market concentration, makes the M&A side have an increasingly control to the marketing, causes a certain monopoly and it also does harm to the social welfare.
