经济政策不确定性对进口技术复杂度的影响

The Impact of Economic Policy Uncertainty on Import Technical Sophistication

技术进步是一国经济发展的重要动力。在经济政策不确定性不断攀升的背景下,研究其对进口技术复杂度存在何种影响愈发重要。本文明确了经济政策不确定性对进口技术复杂度的影响机理,即机遇激励效应、出口效应和技术创新效应,并基于22个典型国家的数据构建计量模型展开实证。实证结果表明,经济政策不确定性对进口技术复杂度存在正向促进作用,经济政策不确定性对进口技术复杂度的促进作用在发达国家和发展中国家间存在差异。

Technological progress is an important driving force for a country’s economic development.With rising uncertainties arising from economic policies,it is even more important to study how it affects the complexity of import technology.This paper firstly clarifies the impact mechanism of economic policy uncertainty on import technical sophistication,which involves opportunity incentive effect,export effect and technological innovation effect.Based on the data of 22 typical countries,an econometric model is built to conduct empirical study.The results show that economic policy uncertainty has a positive effect on import technical sophistication and the effect in developed countries is different from that in developing countries.
