摘要

我们研究无形投资如何改变韩国经济增长的来源。在构建了一个新的行业层面的无形资产数据集后，我们估计了1981-2008年无形密集型产业和其他产业对总生产率增长的贡献。无形密集型产业对总劳动生产率增长的贡献显著增加，而其他产业的贡献则大幅下降。无形密集型产业贡献的增加主要与全要素生产率的增长有关，而与投入的增长无关。由此可见，与这些产业的无形投资相关的革新有可能成为韩国生产率增长的新源泉。

Intangible Investment and Changing Sources of Growth in Korea

We examine how intangible investments change the sources of growth in the Korean economy. After constructing a novel industry-level data set on intangibles, we estimate the contribution of intangible-intensive industries and other industries to aggregate productivity growth in 1981–2008. The contribution of intangible-intensive industries to aggregate labour productivity growth has significantly increased, whereas that of other industries has substantially decreased. The increased contribution of intangible-intensive industries is mainly associated with total factor productivity growth rather than with input growth. This suggests that innovations related to intangible investments in these industries might become a new key source of productivity growth in Korea.

期刊介绍： Started in 1950 by a group of leading Japanese economists under the title The Economic Studies Quarterly, the journal became the official publication of the Japanese Economic Association in 1959. As its successor, The Japanese Economic Review has become the Japanese counterpart of The American Economic Review, publishing substantial economic analysis of the highest quality across the whole field of economics from researchers both within and outside Japan. It also welcomes innovative and thought-provoking contributions with strong relevance to real economic issues, whether political, theoretical or policy-oriented.
