Global issues, such as resource depletion, reduction of greenhouse emissions, etc., have been raised. Environmental issues regarding resources and energy are addressed by various industries that provide products and services. However, industries related to the environment have been separated and controlled. Industries related to the environment exist internationally. The Initiative of the environmental industry is the same as the final objective for protecting the environment, but it is different according to the subcategories or indicators of the industry. In this study, the economic effects of the uni-materialization-related industry on Korea by using the inter-industry related to the pollution prevention were analyzed in accordance with using I-O methodology, reflected by a sector of I-O. This study analyzed the unimaterialization industry being specified as exogenous in order to identify the economic effects of the industry on other industries, using the 2014 I-O table data. The economic effects include production, value-adding and employmentinducing, supply-shortage, price-pervasive, and analysis of inter-industrial linkage. The results of the analysis concluded that primary metal products are highest in the production-inducing effect, whereas wholesale and retail trade is the highest in value-added inducing and employment-inducing effects. Construction is the highest in the supply-shortage effects, and other precision instruments are the highest in price-pervasive effects. Based on these results, although the unimaterialization- related industry plays a large role in intermediary products, it is necessary to promote investment in materials and components industries to increase the technological competitiveness of the uni-materialization-related industry that are still highly dependent on imports. Also this study has a limitation that draws economic effects of the industry related to exact resource circulation because of no systematic categories of environmental industries.
