ABSTRACT

Patent-intensive industries can promote high-quality development of economy; however, they also generate the environmental pollution. Therefore, it is necessary to evaluate their green innovation efficiency (GIE), and it is beneficial to improve the GIE of pantent-intensive industries. We treat the patent-intensive industries as the research objects, in which the new equipment manufactruing is more representative. Based on the projection pursuit model and the stochastic frontier model, we measure the GIE of the new equipment manufacturing and explore the factors affecting GIE. Also, we analyze the dynamic evolution trend of GIE of the new equipment manufacturing based on the dynamic evaluation model with speed characteristics. The research results demonstrate that there is still space for improvement in GIE of the new equipment manufacturing to a certain extent. The GIE of different new equipment manufacturing has obvious differences, and the development is uneven. R&D investment intensity and industry market competition have a positive effect on GIE, while government R&D support and external R&D expenditures have negative influence on GIE. The dynamic GIE of the new equipment manufacturing shows the fluctuating trend over time. The research conclusions provide implications for patent-intensive industries to increase GIE and achieve sustainable development.

摘要

专利密集型产业促进经济高质量发展；然而，它们也造成环境污染。因此，有必要对其绿色创新效率(GIE)进行评估，有利于提高裤密集型产业的GIE。我们以专利密集型产业为研究对象，其中新型装备制造更具代表性。基于投影追踪模型和随机前沿模型，我们测度了新装备制造的GIE，探讨了影响GIE的因素。同时，基于具有速度特性的动态评价模型，分析了新型装备制造GIE的动态演化趋势。研究结果表明，新装备制造的GIE在一定程度上仍有提升空间。不同新装备制造的GIE差异明显，发展不平衡。R&D投资强度和行业市场竞争对GIE具有正向影响，而政府R&D支持和外部R&D支出对GIE具有负向影响。新装备制造业的动态GIE随着时间的推移呈现波动趋势。研究结论为专利密集型产业增加GIE和实现可持续发展提供了启示。D投资强度和行业市场竞争对GIE具有正向影响，而政府R&D支持和外部R&D支出对GIE具有负向影响。新装备制造业的动态GIE随着时间的推移呈现波动趋势。研究结论为专利密集型产业增加GIE和实现可持续发展提供了启示。D投资强度和行业市场竞争对GIE具有正向影响，而政府R&D支持和外部R&D支出对GIE具有负向影响。新装备制造业的动态GIE随着时间的推移呈现波动趋势。研究结论为专利密集型产业增加GIE和实现可持续发展提供了启示。
