Unlocking machine learning for social sciences: The case for identifying Industry 4.0 adoption across business restructuring events
本文提出一个使用STATA软件中机器学习方法识别欧洲企业重组事件中工业4.0技术采纳的框架，为社会科学研究者提供易用的工具。
In recent years, advancements in machine learning (ML) have facilitated the utilisation of big data across various academic disciplines. Nonetheless, these techniques still require a high-level of programming and data science expertise, making them inaccessible to many researchers and hindering the potential for knowledge advancements. This paper presents a framework for identifying the adoption of Industry 4.0 (I4.0) technologies among European firms that have undergone restructuring events. Existing studies on I4.0 adoption rely on diverse data sources at different levels of aggregation (e.g., countries, sectors, firms), spanning various time periods and technological domains. While this diversity often complicates result comparison, it also drives researchers and institutions to explore new data sources to assess technology adoption. Our identification methodology is based on the implementation of ML techniques using STATA, a well-established and user-friendly statistical software. We offer a step-by-step guide based on recently developed commands, allowing for comparison of model performance and analysis of model features. Our findings underscore the potential of ML algorithms as a robust tool for collecting new firm-level data on I4.0 adoption. Specifically, we observe that business restructuring events predicted as I4.0-related conform to adoption patterns identified in prior studies, across countries, sectors and over time.
