题目:数据资本和高质量发展路径

TitleDigitalized Factors of Production and High-Quality Development

主讲人:徐翔

Speaker:Xiang XU

Abstract

本文提出数据资本的概念,并与传统意义上的ICT资本相区分。本文通过构建包含数据资本的经济增长模型,分析信息和数据这一类新的生产要素对于经济增长的直接影响和溢出效应,及其与ICT资本和传统资本之间的作用关系。通过对于模型的求解本文发现,从供给侧提升经济发展质量的关键在于同步提高数据资本投入和信息化水平,数据资本对于经济增长的溢出效应的大小则取决于其对于一般生产技术和数据处理技术的影响系数。具体地,本文发现现有研究通常采用的可测度的全要素生产率高于剥离数据资本后的实际全要素生产率,并提供了支持这一判断的实证证据。本文还发现,将数据资本和ICT资本相区分后,均衡中的稳态增长率比单纯考虑ICT资本时有所降低,这与近年来实证研究的反馈相一致。

In this paper we define a new factor of production: digital capital, and separate it from the capital of information and communication technology (ICT). We construct an endogenous growth model that inputs digital capital to study its direct growth effect and spillover effect, and its relationship with the ICT capital in the production process. By solving the model, we find that the key to improve the quality of economic growth is to simultaneously increase investment in both ICT and digital resources. We also find that the magnitude of digital capital’s spillover to economic growth is decided by its impacts on general production technology and data processing technology. More specifically, we find that measured total factor productivity (TFP) used by most existing empirical studies are higher than the ‘real’ TFP if the impact of digital capital is considered. The separation of digital capital from ICT capital actually reduces the steady-state economic growth rate, which is in line with the results of recent empirical studies.
