摘要
本文以属于战略性新兴产业的A股上市公司为研究对象,使用门限面板模型研究了研发投入对成长性的非线性影响。研究结果表明,研发投入强度对战略性新兴产业的成长性存在显著的门限效应,随着研发强度的增加,其对成长性的促进作用表现出边际递减的规律。进一步基于空间异质性视角进行研究,结果表明:在东部、中部和西部地区分别存在唯一的门限值,在东部地区,研发强度对战略性新兴产业成长性始终表现为促进作用,而在中西部地区,研发强度一旦超过门限值,其对战略性新兴产业成长性转变为抑制作用。
Based on the listed companies in strategic emerging industries in China, this paper examines the non- linear relationship between R＆D input intensity and the growth of strategic emerging industries by using Panel Threshold Model. The results show that R＆D input intensity has two threshold effect on the growth of strategic emerging industries, it has an positive effect of diminishing marginal effi- ciency on the growth of strategic emerging industries. Furthermore, R＆D input intensity has an spatial heterogeneity on the threshold effect of the strategic emerging industries＇ growth. R＆D input intensity has a positive effect on the growth of strategic emerging industries in the eastern regions, while in the western and central regions, R＆D input intensity has a negative effect on the growth of strategic emerging industries when it is bigger than the threshold value.
