英文摘要：

This paper estimates the demotic and foreign enterprises＇R＆D efficiency, technical efficiency and scale efficiency of the six sub-trades of our electron and communication equipment manufacturing industry, using the data from 2002 to 2010 by method of Data Envelopment Analysis （DEA）. Comparing the three sub-trades which get higher efficiencies and analy- zing the reasons, result shows that the scale and the structure of R＆D investment and the way to obtain advanced technology are the main factors influencing the efficiency between demotic and foreign enterprises, and discusses corresponding counter- measures to provide useful ideas to improve the level of our electron and communication equipment manufacturing industry.
