物联网新技术采纳与企业绩效的关系机制——基于Heckman两阶段模型的实证

The Relationship Mechanism between New IOT's Technology Adoption and Enterprise Performance——Based on Heckman Two-stage Model

从物联网传统技术应用经验丰富的物流、港口和航运等行业,分别获取30家物联网新技术采纳者和未采纳者的绩效数据,基于赫克曼两阶段回归模型,分析物联网新技术采纳和企业绩效的关系机制。实证研究发现,物联网新技术采纳能够显著提升企业利润绩效,存货周转率和成本收入比对物联网新技术采纳有显著影响,存货周转率低和成本收入比高的企业更倾向于采纳物联网新技术,财务松弛度对物联网新技术采纳的影响不显著。此外,为了解决新技术采纳企业和未采纳企业的自我选择效应问题,构建基于选择模式的利润分拆式模型,分析结果表明,采纳物联网新技术的企业能够通过降低成本收入比获得更好利润绩效,具有不可观测优势的企业更有机会通过新技术采纳获得更高利润收益。

The performance data of 30 new IOT’s technology users and non-adopters respectively is obtained from the logistics,port and shipping industries with rich application experience of traditional IOT’s technology,and based on Heckman two-stage regression model,the relationship mechanism between new IOT’s technology adoption and business performance is analyzed. The empirical research find that the adoption of new IOT’s technology can improve the profit performance of enterprises,both inventory turnover and cost to income ratio have a significant impact on the adoption of new technology,the enterprises with low inventory turnover and high cost to income ratio are more inclined to adopt the new IOT’s technology,and the impact of financial slack on new technology adoption is not significant. In addition,in order to solve the self-selection effect problem of new IOT’s technology adopter and unadopter,the profit separation model based on the selection model is constructed and the analysis results show that the enterprises adopting the new IOT’s technology can obtain better profit performance by reducing the cost to income ratio,and the enterprises with unobservable advantages have more opportunities to adopt new technology to obtain higher profits.
