建設産業의 經濟的 波及效果에 관한 硏究

Abstract

The construction industry in Korea is in a very difficult situation by opening the Construction License leading to deepening the competition of orders, a series of bankruptcies of construction firms, and opening the domestic construction maket to the world by the tendency of openness. The first stage in economic development, at the early 1960s, the construction industry occupied less than 5% of GDP. However, past 50 years, it has been contributing to national economy in a great measure. In 1990s, it had occupied over 13% of national economy of weight, over 9% in 2000s, but contribution rate for economic development had been all the way down from 20.2% in 2003 to 0.2% in 2005. From this point of view, the purpose of this study is to emphasize the importance of construction industry promoting the image, and suggesting the vision and role of future construction industry by 2 ways. First, it divides the structural change of construction industry into industry structure and competition structure, and derives the problem. Second, it does construction industry feasibility study of level of contribution to the national economy and ripple effect through Time Series analysis and Input Output analysis. The way and structure of this study is as follows. It takes construction industry into consideration as of contribution rate and the role of national economy, then suggests correlation between construction industry-related variable and major economy variables by simple statistical analysis such as picture or table. The competition structure of construction industry is going to be analyzed by high-ranked firm k , degree of concentration rate CRk. Time Series analysis will be used to understand between construction investment and other macroeconomic variables. Input Output analysis will be used to understand economical ripple effect. Followed by the introductory chapter 1, chapter 2, the concepts and present situation of construction industry tells the theoretical consideration and introduction of construction industry. It sets definition and concepts of construction industry, searches the scope of constructional activities through the classification system of construction industry, understands the industrial characteristics comparing with other industries, and looks into situation of domestic construction industry at the basis of 2004. In chapter 3, first of all, it studies the structural change of construction industry by dividing demand structure and supply structure, then analyzes the market occupancy of high-ranked 3,5, and 10 companies through the analysis of the level of market concentration of competition structure of construction industry. Finally, it suggests the problem of construction industry according to the obtained results. In chapter 4, firstly, it analyzes the causal relationship between the construction investment and other macroeconomic variables through Time Series analysis to demonstrate the role of national economy of construction industry, then analyzes economic structure of construction industry , an inter-industry relation effect, and the economic ripple effect by using an inter-industry relation table. Finally, emphasizes the importance and the image of construction industry. As a conclusion, chapter 5 summarizes the whole discussion, and suggests the role and vision of future construction industry corresponding with the changes of domestic and overseas environment. The future construction industry which directly undertakes the very important role for the expansion of social overhead capital(SOC) that is the basis of national competitiveness, and the expansion of the environment-related facilities that is keeping the earth. With similar coherence, construction industry continually maintain its value as a life-close style industry because we need some space where we can live with family, take a rest, and work as long as human being live. The construction industry also builds SOC which is the basis of industry activities as a key industry backing up the nation and national economic development. Besides those things, it is also an essential industry for futuristic industries such as space and ocean development, underground development, and making use of undeveloped resources. Especially in case of considerable improvement between South and North Korea relationship or of unification, construction industry will be the leading industry for building a national basis facilities. The future of Korea's construction industry will be changed as the leading industry deploying at the world market with reliability and power of competitiveness. For this, it has to be born again as a new industry with state-of-the-art technology connected with automation technology such as information technology(IT), environment technology (ET), robot technology etc. It also has to positively cope with and adapt itself to the paradigm changes of construction industry, then it will play an important role as the motive power that is leading the Korean economy for the 21st century. Lastly, this study mainly uses an Input Output analysis based on 2000 inter-industry relation table for explaining the economic ripple effect. In terms of an inter-industry relation table, it has a shortcoming in making because it takes a long time to do and that is the limit against timely manner. Later on, I hope that there will be a better way of analysis and it contribute to the development of construction industry by propelling the study which can assume the economic effect of construction industry.
