This article analyzed the direct impact of resource inputs on business performances of Korean environmental companies conducting R&D, and the mediation effects of product-, process-, organization-, marketing-innovations between resource inputs and business performances. We conducted the mediation analysis using SPSS and Process Macro, based on a survey data from the Korean environmental companies. The article found that ① resource inputs have directly had a positive impact on business performances, and ② innovations have mediated them. ③ But among 4 types of innovations, the only mediation effect of organization-innovation has been verified, and the others have not appeared. Considering the above results, the following policy implications can be suggested. ① It is necessary to reinforce related policies so that companies can improve business performances through innovation. ② The government needs to carry out the prudent supporting policies so that innovations in product, process, and marketing can lead to business performances. This article has the limitation of using the survey data, and needs further researches on the sectoral system of innovation for Korean environmental industry.

This article analyzes the influence of sectoral system of innovation(i.e. technological regime, market demand, networks, and institution) on innovative performances(i.e. product-, process-, organizational-, marketing-, and environmental- innovation) in Korean environmental industry, conducting a multiple regression analysis based on survey data from 201 Korean environmental companies. As the results, product innovation is positively influenced by internal technology accumulation and market demand response, while not affected by external knowledge utilization, market competition, networks among market and non-market agents, government support and regulation. Process innovation is positively influenced by internal technology accumulation, networks among non-market agents and regulation, but not by external knowledge utilization, market demand response, market competition, networks among market agents, and government support. While organizational innovation is positively influenced by internal technology accumulation, external knowledge utilization and regulation, it is not affected by market demand response, market competition, networks among market and non-market agents, and government support. While marketing innovation is positively influenced by internal technology accumulation, networks among non-market agents, and government support, it is not affected by external knowledge utilization, market demand response, market competition, networks among market agents, and regulation. Environmental innovation is positively influenced by external knowledge utilization and regulation, but negatively influenced by market competition. It is not affected by internal technology accumulation, market demand response, networks among market and non-market agents, and government support. Such results suggests the following policy implications. First, it is necessary to expand the sphere of relating markets through the application of convergence technology, new regulations, and overseas markets. Second, reinforcing ecosystems among environmental market agents through demand-linked joint R&D should be revitalized. Third, it is needed to strengthen more supporting policies rather than regulation. This article has the limitation of using the survey data. And further researches on the environmental sectoral system of innovation structure itself will be tried.
