本文通过偏最小二乘(PLS)回归法分析了东北三省高技术产业技术创新能力的影响因素,并利用变量投影重要性指标(VIP)考察了技术创新能力各影响因素的重要程度。结果表明,R&D经费内部支出、新产品开发经费、科研人员数、R&D人员全时当量和消化吸收经费支出是影响技术创新能力的重要因素。
In this paper, the influencing factors of technological innovation capability of high-tech industries in three provinces of Northeast China were analyzed by partial least squares (PLS) regression method. The importance of each influencing factor of technological innovation ability was examined by using variable projection importance index (VIP). The results show that the internal expenditure of R & D funds, the expenditure of new product development, the number of scientific researchers, the full time equivalent of R & D personnel and the expenditure of digestion and absorption are the important factors that affect the ability of technological innovation.
