国外技术引进、经济增长方式转变与异质吸收能力——基于中国省际面板数据的门槛检验

Technology Import,Transformation of Economic Growth Pattern and Heterogeneous Absorptive Capacity:A Threshold Test Based on Interprovincial Panel Data in China

国外技术引进作为后发经济体推进自主创新、实现技术进步的重要渠道,受本土吸收能力等因素的影响,对转变经济增长方式的作用较为复杂。利用我国省际面板数据进行实证研究发现:国外技术引进对我国经济增长方式转变的促进作用在异质吸收能力影响下呈现出区域差异,积极而显著的影响效应发生在东部地区,而非中部和西部地区。以技术获取能力、技术消化能力、技术应用能力为维度的异质吸收能力存在非线性门槛特征,只有在高于门槛水平的地区,技术引进对经济增长方式转变才发挥显著的正向作用。在此门槛条件下,将异质吸收能力的空间类型划分为完全吸收区、不完全吸收区、不良吸收区,"十五"末至"十二五"末期间,不良吸收区缩小至点状分布,不完全吸收区由面到片呈现区域性分布,完全吸收区由点到面、由东向西扩张并成为分布范围最广的空间类型。

Based on the interprovincial panel data,this paper conducts the empirical study and finds that the positive effect of foreign technology import on the transformation of economic growth pattern shows regional differences under the influence of heterogeneous absorptive capacity. Active and significant effects occur in Eastern China rather than Central and Western China. There also exists nonlinear threshold effect. Only in regions where the absorptive capacity is higher than the threshold level,does the technology import have a significant positive effect on the transformation of economic growth pattern. On the threshold condition of technology absorptive capacity,the spatial types are divided into complete absorption areas,incomplete absorption areas and poor absorption areas. During the inspection period,the distribution range of the incomplete absorption area is greatly reduced,and the complete absorption area has been the most widely distributed space type.
