摘要

本研究考察了印度中高技术产业企业的技术采购、内部研发和专利活动之间的关系。本研究以2005年产品前和产品后专利修正案为依据，分为1995-2005年和2006-2015年两个时期。我们分别采用固定效应和随机效应的负二项模型来估计技术购买对研发和专利活动的影响。研发方程的估计表明技术购买与内部研发之间存在互补关系。然而，专利方程的估计表明内部和技术购买之间存在替代关系。此外，我们发现内部研发、技术采购和专利活动之间呈倒u型关系。而企业内部研发与技术采购之间的交互作用正向调节了这种非线性关系。最后，我们的估计结果对不同的行业和时期是敏感的。

TECHNOLOGY PURCHASE, IN-HOUSE R&D, AND PATENTING: AN EMPIRICAL ANALYSIS OF FIRMS IN HIGH- AND MEDIUM-TECHNOLOGY INDUSTRIES IN INDIA

This study examines the relationship between technology purchase, in-house R&D, and patenting activities of firms in India’s high- and medium-technology industries. The study is divided into two periods, i.e., 1995–2005 and 2006–2015, based on the pre- and post-product patent amendment 1 act, 2005. We employ a negative binomial model with fixed and random effects to estimate the impact of technology purchase over R&D and patenting activity, respectively. The estimates of the R&D equation suggest a complementary relationship between technology purchase and in-house R&D. However, the estimates of the patents equation suggest a substitute relationship between in-house and technology purchase. Further, we find an inverted U-shaped relationship between in-house R&D, technology purchase, and patenting activities. However, the interaction between in-house R&D and technology purchase positively moderates the nonlinear relationships. Lastly, our estimated result is sensitive to different industries and periods.

期刊介绍： The International Journal of Innovation (IJIM) is the official journal of the International Society of Professional Innovation Management (ISPIM). Both the IJIM and ISPIM adopt a multi-disciplinary approach to addressing the many challenges of managing innovation, rather than a narrow focus on a single aspect such as technology, R&D or new product development. Both are also international, inclusive & practical, and encourage active interaction between academics, managers and consultants.
