摘要
:发展中国家的政府应该支持技术采用还是促进创新?在不同的发展阶段,答案又会发生怎样的变化?为了回答这些问题,我们对韩国创造增长奇迹时期国内外企业之间的技术转让合同进行了数字化处理,其中包含有关技术价格的新信息。我们发现,当国内外企业的生产率差距较小时,1)采用费用较高;2)采用带来的生产率增长小于创新带来的生产率增长;3)企业更倾向于投资创新而非采用。受这些发现的启发,我们建立了一个具有内生采用和创新决策的两国增长模型。外国企业可以以内生费用出售技术,将与国内企业的激烈竞争导致的未来利润损失内部化。采用和创新带来的生产率收益取决于与外国企业的生产率差距,这使得采用和创新补贴的效果也随差距而变化。我们对模型进行了估计,并定量研究了若干政策在过渡动态过程中的效果。我们对韩国自 1973 年以来的技术政策进行了评估,这些政策从采用补贴开始,随着韩国企业的生产率与国际竞争对手的生产率趋同,转为创新补贴。我们的研究结果表明,这种依赖于国家的政策将消费等值福利提高了 4.84%,高于自始至终只补贴创新或采用的政策。此外,1985 年,当韩国的国内生产总值达到日本的 55% 时,从采用补贴转向创新补贴是最佳选择。摘要:本文提出了一种 "资本嵌入式创新"(CEI)的衡量方法。该指标通过将美国专利商标局的专利描述与维基百科的资本货物描述相匹配,计算出不同资本货物所申请的专利数量。利用 O*NET 中资本货物集的职业级变化,我们发现常规职业的 CEI 指标较小。此外,我们还强调了 CEI 在资本货物与职业关系中的不同影响。当资本品发挥与职业任务相同的功能时(任务替代资本),CEI 对职业的影响就会更大。 摘要:我们研究了战后一个发展中国家采用外国技术以及由此产生的本地溢出效应是如何促进后期工业化的。我们利用韩国企业层面的新颖历史数据,提供了三个经验性发现:采用者的直接生产率收益、采用带来的本地生产率溢出效应以及企业采用决策的互补性。基于这些发现,我们建立了一个动态空间模型,其中包含企业的技术采用决策和本地溢出效应。溢出效应促使企业的技术采用决策具有动态互补性。由于这种互补性,该模型可能具有多种稳定状态。临时性的技术采用补贴可以使经济进入新的过渡路径,从而收敛到生产率更高的稳定状态,从而产生永久性的影响。我们根据微观数据和计量经济学估算结果对模型进行了校准。我们评估了韩国政府在 20 世纪 70 年代临时向重型制造企业提供采用补贴政策的效果。与成功实现工业化的稳定状态相比,如果不提供技术采用补贴,韩国将趋于工业化程度较低的稳定状态,重型制造业在 GDP 中的比重将下降 15 个百分点,总体福利将下降 10%。因此,对技术采用的临时补贴具有永久性影响。
From Adoption to Innovation: State-Dependent Technology Policy in Developing Countries
: Should governments in developing countries support technology adoption or promote innovation? And how does the answer change over different stages of development? To answer these questions, we digitize the universe of technology transfer contracts between domestic and foreign firms in South Korea during its growth miracle period, which has novel information on the price of technologies. We find that, when the productivity gap between domestic and foreign firms is small, 1) the adoption fee is high, 2) the productivity growth from adoption is smaller than that from innovation, 3) firms are more likely to invest in innovation than adoption. Motivated by these findings, we build a two-country growth model with endogenous adoption and innovation decisions. Foreign firms can sell technologies for an endogenous fee, internalizing the future loss of profit due to stronger competition with domestic firms. The productivity gains from adoption and innovation depend on the productivity gap with foreign firms, which makes the effects of adoption and innovation subsidies also vary with the gap. We estimate the model and quantitatively investigate the effect of several policies along the transitional dynamics. We evaluate Korea's technology policies since 1973, which started with an adoption subsidy and shifted to an innovation subsidy as the productivity of Korean firms converged with that of international competitors. Our result suggests that this state-dependent policy increased consumption-equivalent welfare by 4.84%, which is more than subsidizing only innovation or adoption throughout. Furthermore, it was optimal to switch from an adoption subsidy to an innovation subsidy in 1985 when Korea's GDP reached 55% of Japan's.

Furthermore, we highlight the heterogeneous effects of CEI across the capital good-occupation relationship.
