The Productivity of Listed Companies of Computers and Related Equipment Manufacturing Industry

Indicators system of China's computer manufacturing enterprises of listed companies in Shanghai and Shenzhen can be established to reflect the efficiency of production, which accord to the number of employees, fixed assets and other economic data. Integrated data envelopment analysis (DEA) models are used, combining with evaluation and statistical tests of Synthetic Average method, Borda method, Copeland method and Fuzzy Borda method (SABCB Method). The productivities and returns to scale (RTS) of these computer companies can be figured out. Some results could be obtained through the empirical analysis: firstly, productivities of China's computer manufacturers are acceptable in general, although there are still great differentiations among them; secondly, due to the lack of outputs, RTS in some enterprises are decreasing; thirdly, it is currently urgent task that most of computer manufacturers continue to refine and deepen specialization transform existing business processes.
