摘要
知识的流动与循环有利于充分利用国内外不断累积的存量知识,推动自主创新与经济高质量发展。而关于自贸区引领的对外开放对低碳技术知识流动的作用机制研究却较少有研究关注到。本文基于低碳专利引文信息构建知识流动指标,使用284地级市2012~2019的面板数据采用多元回归方法实证检验城市对外开放水平对低碳技术知识流动的研究。研究发现对外开放水平能够显著促进国内外低碳技术知识的流动。可能存在的机制是,对外开放能够促进产业结构升级及外商直接投资的增加,进而促进低碳技术知识流动。
The flow and circulation of knowledge are conducive to making full use of the accumulated knowledge at home and abroad to promote independent innovation and high-quality economic development. However, few studies have paid attention to the mechanism of the opening-up led by free trade zones on the flow of low-carbon technology knowledge. This article constructs a knowledge flow index based on low-carbon patent citation information, and uses panel data from 284 prefecture-level cities from 2012 to 2019 to empirically test the impact of city opening-up levels on low-carbon technology knowledge flows using multiple regression methods. The study found that the level of openness to the outside world can significantly promote the flow of low-carbon technology knowledge at home and abroad. The possible mechanism is that opening up to the outside world can promote the upgrading of industrial structure and the increase of foreign direct investment, thereby promoting the flow of low-carbon technology knowledge.
