Research of the Efficiency of High-Tech Industry Based on DEA Model: Evidence from China

摘要

High-tech industry of a nation is the determinants of the international competitiveness. This paper analyzed the input-output efficiency of 15 high-tech industries using DEA methodology based on the data of "Basic Statistics on Scientific and Technological Activities Funds of Large and Medium-sized Industrial Enterprises in High-tech Industry (2008)". The empirical results indicate that, under the evaluation system whose main output indicators are short-term economic efficiency and the number of patents, electronic computers and office equipments is relatively the most efficient, secondly medical and pharmaceutical products, medical treatment instrument and meter, thirdly electron and communicate equipments, and aviation and aircrafts manufacturing is relatively the least efficient.
