Recently, major countries have emphasized the development of high-tech manufacturing industries to sustainable economic growth and preempt technology hegemony in the era of the 4th industrial revolution. Moreover, at a time when global protection trade stocks are intensifying and China's technology-intensive industry export competitiveness is strengthening, it is important to identify the global position of Korea's high-tech material parts industry and come up with measures to enhance export competitiveness. Therefore, this paper compared and analyzed the export competitiveness of the high-tech material parts industry, focusing on related-significant countries. The results of the study are as follows: The export competitiveness of related-significant countries is high in the order of Market share: China(23.2%), the US(8.1%), Germany(6.0%), Korea(5.8%), Japan(3.9%), TSI: Korea(0.32), China(0.11), Germany(0.01), Japan(-0.30), the US(-0.30), RCA: Korea(1.86), China(1.72), Japan(1.00), the US(0.92), Germany(0.74), EXPY: Korea(119.75), China(110.48), Japan(63.44), the US(60.16), Germany(50.23), HHI: Korea(2,456), Japan(2,393), Germany(2,264), the US(2,024), China(1,929), ESI: China(0.98), Japan(0.56), the US(0.52), Germany(0.42). The implications derived based on the analysis are as follows. First, it is necessary to focus on developing industries in which product advancement is rapidly progressing. Second, it is necessary to reduce the concentration of specific items by diversifying the fields of the high-tech material parts industry. Third, as global semiconductor hegemony competition is intensifying, it is necessary to prepare measures to build stable supply chains and enhance technology capabilities. To this end, active efforts should be made to diversify importing countries, diplomatic efforts of the government, R&D support to increase the localization rate, and human resource development.
