Research of R&D Depreciation for Sustainable Development in South Korea – Focusing Previous COVID-19

Objective: This is research about R&D productivity improvement for sustainable development in South Korea. Recently, there are increasing the considerable importance of R&D productivity for industry and corporation. Theoretical Framework: The R&D productivity index has become an essential factor for sustainable development estimation. For processing, research capital must be estimated firstly. At this time, the research capital is determined basically by the R&D investment and R&D depreciation rate made at each point or year. Therefore, in order to estimate the amount of research capital, firstly the R&D depreciation rate should be estimated that is fitted in proper phase of technology. Method: We can find a depreciation of R&D manufacture industry. The research data used the Korea Evaluation Data (KODATA) in collaboration with the Korea Productivity Center to reflect the technical factors of Korean companies as much as possible. The possibility of using the depreciation rate in this income-maximizing model can be confirmed that use sample of 1,233 and period in 2015-2019 of pre-COVID-19. Results and Discussion: South Korea should consider the fact that investment in the IT and ICT sectors accounts for a high proportion and that the proportion of leading industries is higher than that of the entire industry. In addition, considering that the share of the manufacturing industry is the highest among OECD countries, a separate consideration of the difference from 43.85% will be necessary Research Implication: Skill-intensified counties should consider proper R&D depreciation index that can affect the R&D productivity result. Value: For sustainable development, it is need to take exact R&D depreciation that raise R&D productivity. and this is associated with economic development.
