文章从我国物联网企业技术突破的视角出发,选取2003-2012年我国物联网179家上市公司的数据为研究样本,将其划分为突破性技术企业、创新性技术企业及战略性技术企业三类,通过多值选择模型和倾向得分匹配估计法来探索这三类企业在自主创新和技术引进之间如何抉择,并结合当今物联网技术发展背景,得出我国物联网企业技术突破路径。

The paper, from the perspective of technological breakthrough of Chinese internet of things （IOT） enterprises, selects the data of 179 listed companies in Chinese lOT industry from 2003 to 2012 as the study sample. We classify the companies into three types： breakthrough technology companies, innovative technology companies and strategic technology companies. We carry out the exploration on how these three types of companies making the selection between independent innovation and technology import by employing the multiple value choice model and propensity score matching method. We also draw the path of technological breakthrough of Chinese lOT enterprises by combining with the context of IOT technology development.
