尽管许多管理顾问建议企业可以将部分技术开发活动进行外包,但是对于企业内部R&D与外部技术获取之间的作用性质及其条件却知之甚少。本文构建了一个超越对数创新产出函数,利用中国31个省份的大中型工业企业的创新投入-产出数据检验了企业内部R&D投入、外部R&D投入以及外部技术引进(直接技术利用)之间的替代性和互补性。研究结果表明,当企业具有更强的技术吸收能力、较大的经济规模和具备以往技术转让经验时,内部R&D与外部R&D之间的互补性较强;而企业的R&D投入(技术开发)与外部技术引进(直接技术利用)之间一般呈现出替代性。可见企业在不同的技术活动阶段、采用不同的技术活动形式时,外部技术的替代性与互补性有所不同。
Although many management consultants recommend that companies can outsource part of their technology development activities, little is known about the nature of the role and conditions of R & D and external technology acquisition within an organization. In this paper, we construct an innovation output function beyond logarithm and use the innovation input-output data of large and medium-sized industrial enterprises in 31 provinces in China to test the internal R & D investment, external R & D investment and external technology introduction (direct technology utilization) The alternative and complementarity. The results show that the internal R & D and external R & D are highly complementary when the enterprises have stronger technology absorptivity, larger economic scale and experience of technology transfer. However, the R & D investment (technology development) The introduction of external technology (direct technology utilization) generally presents an alternative between. Visible enterprises in different stages of technology activities, the use of different forms of technical activities, the external technology alternative and complementarity are different.
