성향점수매칭(PSM)과 이중차분법(DID)을 활용한 환경기술개발사업의 기업지원 효과 분석

초록

In this study, a quantitative analysis was conducted by using propensity score matching and difference-in-differences method to measure how much the government's environmental research and development (R&D) support affects corporate management performance. Based on corporate financial statements from 2011 to 2020, the average treatment effect was analyzed for four years after companies received government support. The analysis results confirmed that, although a time lag exists, the number of employees, growth rate of R&D expenditure, sales growth rate, total asset growth rate, and return on asset of government-supported companies had increased compared to companies that were not receiving government support. These results are meaningful in that they confirmed the justification for supporting environmental R&D projects as a complement to market failure, and that they indicate that continuous government support, such as follow-up R&D, is necessary for environmental companies to implement technological innovation.
