본 연구에서는 DEA 및 DEA윈도우분석 방법을 활용하여 중국통신기업의 효율성 변화를 분석하였다. 분석에 활용된 자료는 차이나텔레콤차이나넷콤차이나모빌차이나유니콤의 4개 기업이다. 대표적인 투입요소로는 고용자수고정자산비용이었고, 산출요소는 매출액이었다. 중국 통신업계에 있어서 급격한 제도적 변화를 가져온 2002년 통신시장재편의 전후인 2001-2005년까지의 자료를 분석한 결과를 요약하면 다음과 같다.첫째, 연차별 효율성 변화분석을 보면, 통신시장 재편으로 전후로 해서 기술효율성과 순수기술효율성에는 급격한 변화가 있었으며, 규모의 효율성은 꾸준히 상승하였다. 둘째, 효율성을 변화시킨 직접적인 원인은 고용자수의 차이에 있었다. 특히 통신구조 특성상 고용자수가 많은 유선통신사업자의 효율성이 상대적으로 떨어졌다. 셋째, 시대의 흐름에 따른 효율성 변동의 측면만을 강조한다면 윈도우즈 기법을 사용한 시대별 효율성 측정이 더 적합하다고 보여 진다. 향후 중국이 통신시장을 효율화하기 위해서는 시장과 기술의 두 차원에서 정보화정책과 IT정책을 통합한 정보통신정책을 모색할 필요가 있다.

The Era Efficiency Variance Analysis of the China State Ownership Telecommunications Enterprise: Using Data Envelope Analysis. Lee, Jae-Ho In this research, the efficiency change of the China communications company dealer was analyzed by using DEA and DEA window analytical method. The analysis materials is enterprise of the China Telecom, China Netcom, China Mobile, China Unicom. The input element is the employee, fixed asset, expense. The output element is the revenue. The analyzed result is as follows. 1) The chinese telecom restructuring has produced an overall positive effect on the efficiency of the sector. However, there is quite a significant gap in efficiency between first-comers and late-comers, even though all of them are state-owned enterprise. 2) The number of employees is the most important factor affecting the level of efficiency of a telecom company. 3) The windows technique is more suitable if it emphasizes only the side of the effectiveness change according to the flow of an era. To effectively boost the efficiency of the telecom sector, telecom policy must now address technological evolutions taking place within it, and not just market issues.
