Building on the case of European Union (EU) regions, we study the macroeconomic impact of related diversification. We use an indicator of technological related variety in combination with stochastic frontier estimation and a well-established general equilibrium model to assess the rationale for related diversification and to understand the relevance of different region-specific policies. The results suggest that related diversification has a greater potential for less advanced regions than for more advanced ones. This has interesting implications for industrial policy, calling for a differentiated approach depending on the technological space and level of development of different regions.

技术相关的多元化：一种尺寸并不适合所有欧洲地区

我们以欧盟（EU）地区为例，研究相关多元化对宏观经济的影响。我们使用技术相关多样性指标，结合随机前沿估计和完善的一般均衡模型来评估相关多元化的基本原理，并了解不同地区特定政策的相关性。结果表明，相关多元化对于欠发达地区比先进地区具有更大的潜力。这对产业政策产生了有趣的影响，要求根据不同地区的技术空间和发展水平采取差异化的政策。
