Purpose - Before the economic reforms, the Chinese communication industry was poorly developed. After China's entering to WTO, the Chinese market were gradually opened, domestic companies will be faced with more and more pressures of competition from the world rival countries. As time goes on, the overseas telecommunications companies will occupy the Chinese market with the opening of China Telecommunications market to outside. So this paper focuses on problems and development methods based on the research about the present situation and development methods of communication industry(communication manufacturing industry and communication manufacturing industry) in China. Research design, data, and methodology - This study analyzed the policies of China's entering to WTO. This paper observed previous researches and made an empirical research on Chinese communication industry based on the governmental policies, strategies, books and previous papers with several kinds of clear data announced formally by China authorities. Results - Most recently, reorganization of the communication industry has brought good opportunities for the development of the communication manufacturing enterprises. This paper analyze policy changes of Chinese communication industry, the status of communication manufacturing industry and communication service industry. Finally, this study for further research analyzes the existing problems and puts forward some practicable measures to solve them. Conclusions - Looking ahead, with China's rapid economic development and steady deepening of reform and opening-up, the Chinese communication industry is faced with an even broader prospect of development. Chinese communication industry will be become the pillar one in national economy after 10 years development. Foreign communication companies accelerated investment and progresses to Chinese information and communication markets. Positive ones are more foreign investment, export increase, domestic innovation, communication industry made steep growth. But negative ones are obstacles of domestic companies' development and jobless rate increase etc. Second communication manufacturing industry made good development, but computer and TV related industry made decline in growth. Third, market sizes of internet and mobile services are growing but the size of wired communication services is downsizing gradually. To overcome them, the studies of components or parts of communication manufacturing industry are needed individually. Second China Unicom, China Telecom, China Mobile etc. are Chinese representatives. The sales volumes are very similar at the beginning, but now they are different and make big differences. So the analysis about, their differences and its impact, are needed.

This paper analyses the Korean information and communication technology supply side across the economy using 1995, 2000 and 2003 input-output tables. Input-output analysis considers inter-industry relations in an economy, depicting how the output of one industry goes to another industry where it serves as an input, and thereby makes one industry dependent on another both as customer of output and as supplier of Inputs. It can be evaluated that the recent growth of Korean ICT sector has come from the development of communication service and equipment industry and software industry. Although the high performance and positive revealed comparative advantages in ICT manufacturing sector, the value added and employment in that sector are not satisfactory. It may reflect in part high portion of imported intermediate goods in ICT manufacturing. However, it is fortunate that ICT services, which accounted for relatively high value added, induce the development of ICT manufacturing and follow strong export performance. Moreover, it is expected that the software sector with high value added and employment will be a major driver of ICT growth.

효율성 측정은 일반적으로 상장기업을 중심으로 이루어지고 있으며, 중소기업을 중심으로 한 효율성 연구는 미비하다. 따라서 중소기업의 경쟁력을 강화하기 위해서는 우선 중소기업의 현실을 파악할 필요가 있으며, 이를 위해 본 연구에서는 중소기업의 효율성을 측정하여 경쟁력 강화의 기본 자료로 이용되기를 바라는 측면에서 연구되었다. 효율성 측정은 비율분석이나 회귀분석을 통하여 일반적으로 이루어지고 있으나, 본 연구에서는 이러한 분석방법을 이용하지 않고 DEA(data envelopment analysis)모형이라는 새로운 측정수단을 이용하여 효율성을 측정하였다. 국내 상장 중소제조업을 중심으로 1996년부터 1999년까지의 패널자료를 이용하여 IMF전후의 비효율성을 측정하였다. 연구결과에 의하면 상대적 평균효율치는 도매 및 상품중개업이 68.99%, 영상 음향 및 통신장비 제조업이 60.58%, 음식료품제조업이 91.05%, 자동차 및 트레일러제조업이 85.80%, 제1차금속산업이 88.96%, 펄프 종이 및 종이제품제조업이 96.53%, 화합물 및 화학제품제조업이 78.67%로 나타났다. DEA모형은 서비스 및 비영리단체에서 주로 사용되어 온 효율성 평가방법이나 이를 중소제조업에 처음 적용해 보았으며, 추가적으로 IMF 이전과 이후시점의 효율성을 수치적으로 비교하여 우리나라 중소제조업의 경영효율성을 파악하게 해주었다.

산업 4.0 이전의 많은 제조 방식들이 단순히 생산 라인의 단점을 극복하는 것이 목적이라면, 산업 4.0은 생산 설비 스스로 작업 방식을 결정하여야 한다. 이러한 과정 속에서 FMS, AMS, MAS 등의 제조 방식들이 발전하여 왔으나, 이러한 제조방식들은 기계, agent, 자원 공유 등의 이유로 교착상태가 발생할 수 있다. 이를 해결하기 위해 여러 연구가 진행되어 왔지만, 사람의 개입으로 인해 제조 방식이 동적으로 재구성되는 상황에서 발생되는 교착상태를 방지하는 연구는 미비하다. 본 논문에서는 동적으로 재구성되는 상황의 모델을 제시하며, 이러한 상황에서 발생하는 교착상태를 방지하는 기법을 제안한다. 제안하는 기법은 사람이 개입한 기계의 제조 시간이 변경될 경우 주변 기계들에게 오차 시간 메시지를 브로드캐스트함으로써 생산 제조 시간을 조절한다. 이를 통해 생산 라인의 상황이 변화하더라도 교착상태는 방지할 수 있을 것이라 예상된다.
