Efficiency and Productivity on ICT Industry

ICT 제조업과 서비스업의 효율성과 생산성

Non-parametric method such as technology efficiency, DEA/Window model and Malmquist Productivity Index (MPI) are used to measure efficiency and productivity of ICT (Information and Communication Technology) manufacturing industry and service industry over the period 2007-2011. The results of this paper indicate following: (1) Technology efficiency of the ICT manufacturing industry were found as the range of 0.34 and 0.39 over the sample period. Technology efficiency of the ICT service industry were found as the range of 0.16 and 0.20 over the sample period. (2) The geometric average of the Malmquist TFP indexes on ICT manufacturing industry indicated the productivity improvement an average of 8.3 percent. The geometric average of the Malmquist TFP indexes on ICT service industry indicated the productivity improvement an average of 1.6 percent. (3) TIER analysis result on ICT manufacturing industry showed that optimal bench marking made by storage devices${\rightarrow}$wireless communication equipment${\rightarrow}$broadcasting equipment${\rightarrow}$radio, recording and playback devices${\rightarrow}$computers, printers, video and audio-visual equipment path. TIER analysis result on ICT service industry indicated that optimal bench marking made by computers and packaged software${\rightarrow}$wired communication${\rightarrow}$communication, information, detection equipment${\rightarrow}$consulting and construction for computer systems integration${\rightarrow}$industrial machinery and equipment rental${\rightarrow}$telecommunications reseller${\rightarrow}$system software development and delivery${\rightarrow}$hosting path.

본 연구는 국내 ICT 제조업과 서비스업의 경쟁력 강화를 위한 기초 연구로서 효율성과 생산성 추이 및 생산성의 결정요인을 분석하는 것을 목적으로 하였다. 구체적으로 본 연구는 ICT산업의 효율성 분석을 위해 ICT 제조업 23개 업종과 ICT 서비스업 18개 업종에 대하여 2007년부터 2011년까지 5년간 규모의 수익불변을 가정한 DEA(Data Envelopment Analysis)의 CCR모형과 규모의 수익가변을 가정한 BCC모형을 통해 기술효율성과 순수기술효율성의 정태적 효율성을 살펴보고, 기술효율성에 대한 DEA/Window 분석과 Malmquist 생산성 지수를 이용하여 동태적 효율성을 분석하였다.
