Applications of a “Carry-Over” Enhanced DSBM Intertemporal Technical Efficiency Model on the Taiwanese 5G Industry

Abstract Taiwan has proven itself successful at both inventing the key technologies leading to the development of 5G (fifth generation wireless technology)-related industries and serving as an indispensable link in the burgeoning 5G-industrial global supply chain. This study analyzes the current state of Taiwan’s 5G industry via the utilization the purpose of this study is to the Dynamic Slacks-Based Measure (DSBM). To achieve this purpose, a dynamic-data production process model was developed to analyze the 5G industry’s overall relative efficiency. Results indicate that (1) key chip-producing companies typically experience increased efficiency following 5G R&D industry development investment, and that said companies’ relative efficiency is, indeed, affected positively by R&D investment; and (2) key chip companies’ relative increases of efficiency were higher than those of brand terminal and downstream-industry-category companies, while companies with higher levels of R&D investment exhibited relatively higher and more significant levels of efficiency. Finally, it was discovered that the relative efficiency of Taiwan's 5G-related industries’ R&D investment was, indeed, statistically significant in terms of the Taiwanese government’s industrial policies regarding 5G R&D investment.
