AB - This study aimed to evaluate the R&D efficiency of Daejeon Metropolitan City's regional industries and to derive policy implications for enhancing the competitiveness of regional industries. To achieve this, Data Envelopment Analysis (DEA) and Malmquist Productivity Index (MPI) were employed to analyze the efficiency and productivity changes of 16 Decision-Making Units (DMUs) in Daejeon’s key industries from 2013 to 2022.
The DEA analysis revealed that certain industry groups, such as the Research Industry (2013-2014), Bio Industry (2013-2014), and Metal Industry (2015-2017), demonstrated high efficiency by optimizing resource utilization. These industries were found to effectively maximize outputs by efficiently using resources in their R&D activities. On the other hand, some industries, such as the Knowledge Industry (2013-2014) and Wireless Communication Industry (2015-2017), recorded relatively low efficiency, indicating the need for improvements in resource utilization and operational strategies. The Scale Efficiency (SE) analysis showed that some industries were not operating at an optimal scale. Furthermore, the MPI analysis, which evaluated productivity changes over time, confirmed that technological progress and changes in technical efficiency significantly impacted industry-specific productivity. Efficiency changes over time were recorded as 70.96% (13-'14), 70.317% (15-'17), 68.59% (18-'20), and 76.57% (`21-'22), with a 28.38% improvement potential over ten years.
