Abstract One of the biggest and constant issue in South Korea is Particulate Matter (PM) pollution for several years now. The concern of the public is rapidly increasing because of that PM is designated as carcinogenic substances by WHO and in numerical and visually as well that the situation is hardly getting better, particularly in PM2.5 concentrations. In 2017, the government announced the 'PM Response Strategy Based on Science and Technology (FY2017 -2023)' and continue to expand its R&D budget. The R&D budget for PM area is about KRW 94.2 billion in FY2018 which is about 37.0% increase over the last three years. As its R&D projects are conducted competitively that there is a concern about likely to have an overlapping investment and inefficiency. The purpose of this study is to examine how PM pollution area has evolved in South Korea and globally. Based on the technology category from the policy, we have gathered 536 South Korean R&D projects and 9,260 SCI paper data from 2015 to 2017. The research conducted topic model analysis to chronological and by country, particularly South Korea and China, the changes of main key words in this research field. As a result, it is expected to use as basic data for budget allocation process, policy implication, and international cooperation on PM response strategy.
