摘　　要：基于全国第二次R&D清查数据,本文利用CDM模型对北京市制造业R&D投入的贡献进行了研究,评估其技术创新效果.研究发现,无论是R&D经费投入还是R&D人员投入都对新产品产值有显著影响,并且新产品强度越高的企业劳动生产率也越高,说明R&D投入通过新产品有效地促进了劳动生产率的提高.本文还发现,只有R&D经费内部支出对新产品产值具有显著的影响,可以促进劳动生产率的提高,而R&D经费外部支出的作用并不显著.Based on the second R＆D survey of Beijing, it studied the contribution of R＆D input in Beijing＇s manufac- turing industry. The results find that both R＆D spending and R＆D personnel have significant impact on new product, and higher new product intensity leads to higher labor productivity. Therefore, R＆D input efficiently improves the labor productivity through new product. It also finds that only R＆D internal expenditure has significant influence on new product while R＆D external expenditure has no significant influence.
