摘　　要：明确国防研发投资对经济增长的影响对于中国军民融合发展具有重要意义。本文利用美国1949—2014年的宏观数据,构建联立方程组模型检验美国国防研发投资对经济增长的影响。结果表明:美国国防研发投资通过直接促进社会技术进步和刺激私人部门研发投资两种渠道,对经济增长产生了显著的促进作用。因此,逐渐接近世界技术前沿的中国应该继续加大国防研发投资力度,完善国防技术转移体制机制,推动创新驱动发展。It is important to make clear the impacts of defense R＆D investment on economic growth for promoting civil-military integra- tion in China. In this paper, we employ macro data of USA from 1949 to 2014 and establish a simultaneous equations model to examine the impact of U. S. defense R＆D on economic growth. The results show that the defense R＆D has a significant positive impact on eco- nomic growth through promoting the social technology progress directly as well as stimulating R＆D investment of private sector. Hence, China, which is gradually close to the technology frontier, should continue to increase defense R＆D, improve the institutional regime of defense technology transfer, and promote the innovation-driven development.
