Abstract

IC industry is one of the foundation and core industries of modern information industry. Therefore, the study of this industry has important theoretical and practical significance. The main purpose of this study is to measure the degree of close correlation between the two indexes through correlation analysis of the selected indicators, so as to study the development trend and direction of IC. Based on the theory of induced innovation and the theory of comparative advantage, this paper analyzes the correlation between the profit of the IC industry and the following three indicators by using chart analysis method, covariance analysis method and correlation coefficient analysis method. These three indicators are R&D expenditure, new product development costs and annual export amount of IC. The selected data are mainly from CHINA STATISTICS YEARBOOK ON HIGH-TECHNOLOGY INDUSTRY. Through the research, it is found that the profit of China's IC industry is positively correlated with the first two indicators and negatively correlated with the annual export amount.

IC 산업은 현대 정보기술 산업의 핵심으로 국가의 경제발전을 지원하고, 국가안보를 보장하는 전략적이며 기본적인 선도 산업이다. 따라서 이 분야에 대한 연구는 이론적으로나 현실적으로 매우 중요하다 할 수 있다. 본 연구의 주요목적은 선택된 지표에 대한 관련성분석을 통하여 두 지표 사이의 밀접한 관련정도를 가늠하여 집적회로의 발전추세와 방향을 연구하는 것이다. 본 연구에서는 유도혁신 이론과 비교우위 이론을 바탕으로 차트 분석법, 공분산 분석법, 상관 계수 분석법을 이용하여 중국 IC 산업의 이익과 다음의 3가지 지표 사이의 상관관계를 분석하였다. 분석에 사용된 세 가지 지표는 중국 IC산업의 R&D 지출, 신제품 개발 비용 및 연간 수출량이다. 분석에 사용된 데이터는 "첨단기술 산업에 대한 중국 통계연감" 자료를 사용하였다. 본 연구를 통해, 중국 IC산업의 이익은 R&D 지출비용 및 신제품 개발비와 정의 상관관계를 나타내고, 연간 수출량과 부의 상관관계가 있음을 확인하였다.
