Research Reports

Materials used in the domestic construction industry account for approximately 5.8% of GDP and have a large impact on the overall economy, but sufficient research has not been conducted so far. The purpose of this study is to understand the major construction material industries and analyze how much is actually input into the construction industry in South Korea. The first purpose of the study is to examine the demand for construction materials reflecting the construction economy and to estimate the demand for major construction materials based on the quantity. ․Second is to understand the basic production process of major construction materials and examine the raw material input structure. This study consists of a total of 5 chapters, and each chapter is summarized as follows. ․Chapter 1 explains the background and purpose of the study as an introduction, explains the differences along with consideration of past studies, and discusses the overall composition of the study. The cost structure of the construction industry was analyzed. In order to examine the trend of construction material cost changes in terms of construction cost, construction industry management analysis and construction cost data were used, and at the same time, the input cost of major construction materials by type of construction material market was analyzed from the industrial point of view through the inter-industry table. ․Chapter 3 sets the main construction materials as cement, ready-mixed concrete, aggregate, rebar. In order to examine the production volume and price changes for each material, and to examine the characteristics of the industry, we examine the production method, raw material, and supply method respectively. ․In Chapter 4, basic unit analysis of major construction materials was performed. The unit input structure was reviewed, and the ready-made amount of the construction industry was formed in the form most similar to the process presented in the industrial-related table constituting the construction investment amount, and the input amount was set. do the analysis.
