科技创新影响消费需求的机理研究——基于省际面板数据的空间计量分析

The Mechanism of Scientific and Technological Innovation AffectingConsumer Demand--Spatial Econometric Analysis Based on Panel Data of Provinces

基于2009—2018年我国省际面板数据及空间杜宾模型分析科技创新对消费的影响。研究发现:在创新投入上,人才和资本投入对人均生存消费有显著促进作用,人才投入对人均消费有显著促进作用;在创新层次上,渐进创新和激进创新对人均生存消费和人均享受与发展消费有显著促进作用,渐进创新对人均消费有显著促进作用;在创新环节上,工艺创新对人均享受与发展消费及人均消费有显著促进作用,产品创新对人均生存消费有显著抑制作用;同时,资本投入越强的省份对邻近省份的人均生存消费、人均消费产生正向显著空间溢出效应,渐进创新、激进创新越强的省份对邻近省份的人均生存消费、人均享受与发展消费、人均消费产生正向显著空间溢出效应。

Based on panel data of provinces in China from 2009 to 2018,the Spatial Durbin Model was used to analyze the influence mechanism of scientific and technological innovation on consumption.The research shows that in terms of innovation input,talent and capital inputs have a significant positive effect on per-capita survival consumption,so does talent input on per-capita consumption.At the level of innovation,gradual and radical innovations have a significant positive effect on per-capita survival consumption as well as per-capita enjoyment and development consumption,as does gradual innovation on per-capita consumption.In the links of innovation,process innovation has a significant positive effect on per-capita enjoyment and development consumption as well as per-capita consumption,while product innovation has a significant restraining effect on per-capita survival consumption.The provinces with stronger capital input have significant positive spatial spillover effect on the per-capita consumption and per-capita survival consumption of the neighboring provinces;the provinces with stronger gradual and radical innovation have significant positive spatial spillover effect on the per-capita survival consumption,per-capita enjoyment and development consumption and per-capita consumption of the neighboring provinces.
