摘要

数字化如何改变宏观经济的生产函数？利用企业可以选择技术的模型，我们发现，拥有更多数字资本的部门在附加值与中间投入之间以及资本与劳动力之间表现出更高的替代弹性。这种替代弹性的变化与技术前沿上特定投入技术的更高互补性是一致的。我们进一步表明，技术互补性与数字密集度之间的联系可以通过基于任务的方法加以合理化。在三类数字资本中，只有信息技术和软件/数据库的水平对生产函数有显著影响，而通信技术则没有影响。我们还发现，增值中的数字技术变化是希克斯中性的。

The effects of digitalization on production

How does digitalization transform the macroeconomic production function? Using a model where firms can choose their technology, we find that sectors with more digital capital exhibit a higher elasticity of substitution between value added and intermediate inputs and between capital and labor. This shift in the elasticity of substitution is consistent with a higher complementarity of input-specific technologies on the technology frontier. We further show that the link between technological complementarity and digital intensity can be rationalized using a task-based approach. Out of the three types of digital capital, only the levels of information technology and software/databases have a significant impact on the production function, whereas communication technology has no effects. We also find that digital technical change in value added is Hicks-neutral.

期刊介绍： The European Economic Review (EER) started publishing in 1969 as the first research journal specifically aiming to contribute to the development and application of economics as a science in Europe. As a broad-based professional and international journal, the EER welcomes submissions of applied and theoretical research papers in all fields of economics. The aim of the EER is to contribute to the development of the science of economics and its applications, as well as to improve communication between academic researchers, teachers and policy makers across the European continent and beyond.
