数字化水平与区域经济一体化对日本电子产业出口的影响——以RCEP成员国为例

The Impact of Digitalization Levels and Regional Economic Integration on Japan’s Electronics Industry Exports—A Case Study of RCEP Member Countries

摘要: 本研究旨在实证分析RCEP成员国的数字化水平对日本电子产业出口的影响。基于2012~2022年RCEP成员国贸易数据(HS85分类)，以引力模型为基础构建了OLS与固定效应模型。主回归分析结果表明，数字化水平(ICT指数)对日本电子产业出口具有1%显著性层面的正向影响，证实数字化进程促进了出口增长。稳健性检验结果保持一致，表明数字化效应具有结构性而非短期性特征。从韩国视角的比较分析显示，其数字化促进效应较日本更为显著，推测数字基础设施建设与政策推进速度的差异影响了贸易成果的差异。总体而言，在RCEP框架下，数字化已成为提升日本电子产业竞争力的全新驱动力。

Abstract: This study empirically analyzes the impact of digitalization levels among RCEP member countries on Japan’s electronics industry exports. Based on trade data (HS85 classification) from RCEP member countries spanning 2012~2022, both OLS and fixed-effects models were constructed using gravity models. Primary regression results indicate that digitalization levels (ICT index) exert a positive influence on Japan’s electronics industry exports at the 1% significance level, confirming that digitalization drives export growth. Robustness tests yield consistent results, indicating that the digital effect exhibits structural rather than short-term characteristics. Comparative analysis from the Korean perspective reveals a more pronounced digital promotion effect than in Japan, suggesting that differences in digital infrastructure development and policy implementation pace influence divergent trade outcomes. Overall, within the RCEP framework, digitalization has emerged as a new driving force for enhancing the competitiveness of Japan’s electronics industry.
