技术创新对纺织产业高端化的影响与作用机理——基于全要素生产率视角

Influence and mechanism of technological innovation on high-end textile Industry: Based the perspective of total factor productivity

技术创新是实现产业高端化的关键,而产业高端化的最直接体现之一是全要素生产率的提升。基于2016-2020年92家纺织服装上市企业数据,运用DEA-Malmquist指数法测算全要素生产率变化率,以此揭示纺织产业高端化水平,并实证分析了技术创新对全要素生产率的影响关系与作用机理。研究发现:纺织产业高端化程度偏低,尚处于基础高端化阶段;实证分析表明,技术创新对当期全要素生产率存在负效应,其对全要素生产率的提升作用具有滞后效应,且二者的作用程度在不同所有制性质和管理者结构中存在异质性;进一步研究发现,竞争优势在技术创新当期(滞后期)与全要素生产率之间存在遮掩(完全中介)效应,企业绩效则在技术创新当期(滞后期)与全要素生产率之间均表现为部分中介效应。基于此,针对如何提高纺织产业高端化程度、发挥技术创新滞后效应和动力机制等方面提出了对策建议。

Technological innovation is the key to achieving high end oriented industry, and the most direct embodiment of it is the improvement of TFP. Based on the data of 92 listed enterprise in textile industries during the period of 2016-2020, we measure TFP by using the methods of DEA-Malmquist index to reveal the high-end level of the textile industry, and empirically analyze the impact relationship and mechanism of technological innovation on TFP. The result shows that the high-end level of the textile industry is still in the basic high-end, which is not enough. Empirical analysis shows that the technological innovation has a negative effect on current TFP, and the improvement of technological innovation has a hysteresis effect. For companies in different ownership and managers, technology innovation has heterogeneity on TFP. Further study found that there existed masking effect(full intermediary effects) in terms of competitive advantage between technological innovation(lagging period) and TFP. Moreover, enterprise performance is characterized by partial intermediary effects between technological innovation(lagging period) and TFP. Based on the above results, the authors put forward high-end policy suggestions for how to enhance the degree of high-end, improve hysteresis effect and power mechanism of technological innovation.
