Abstract

In today's economy, one of the most important national indicators of economic growth performance is the country's ability to produce new technology-and use it responsibly and efficiently-for environmental protection or energy conservation, production and consumption in agreement with international standards. The purpose of this study is to identify the Research and Development (R&D) capability in the area of environmentally friendly technologies in China, Japan and Korea over the last twenty years. As the field is very wide, Water-Gas Shift (WGS) reaction technologies were taken as a case study for the purpose of this article. During 1990-2011 a total of 788 papers in the field of WGS technologies were published by scientists in China, Japan and Korea. China was the top producing country with 394 papers (50%) followed by Japan with 250 papers (32%), and Korea with 144 papers (18%). The growth of the literature in the field was found to be exponential in nature for China. The R&D capabilities were found to correlate directly with the Gross Domestic Expenditures on R&D (GERD), Researchers in Full-time equivalents (FTE), and other economic parameters.
