本文将知识密集型服务业分为专业性服务业和技术性服务业,运用关联比例法测算中美两类知识密集型服务业对医药制造业的供给关联强度并进行比较分析.研究发现:美国专业性服务业和技术性服务业对医药制造业的供给关联强度均显著高于中国;在专业性服务业中,美国商务服务业对医药制造业的供给关联强度显著高于中国;在技术性服务业中,美国研究与试验发展业对医药制造业的供给关联强度则显著低于中国,而美国医药企业的研发强度远高于中国.中美医药制造业的发展模式有显著差异,美国医药制造业研发是以企业为主体,更重视企业产品市场化过程的服务,中国医药制造业研发是以研究机构为主体,更重视推动上游研发部门的研究成果向企业转化.%In this paper, We divides the KIBS into professional-based knowledge-intensive business services ( P-KIBS) and technolo-gy-based knowledge-intensive business services ( T-KIBS) . Then we compares the backward linkage ratio between pharmaceutical in-dustry and two types of KIBS in China and America. The results show that the backward linkage ratio between pharmaceutical industry and two types of KIBS in America are significantly higher than that of China. In P-KIBS. The backward linkage ratio between pharmaceu-tical industry and business services is significantly higher than that of China; In T-KIBS, the backward linkage ratio between pharma-ceutical industry and R&D services is significantly lower than that of China, whereas the R&D intensity of American pharmaceutical companies is far higher than that of China. The development model of pharmaceutical industry in China and America have significant difference. In America, the R&D of pharmaceutical industry is oriented by companies and companies pay more attention to the service which support the process of products marketing, while in China, the R&D of pharmaceutical industry is dominated by research institu-tions, and the companies pay more emphasis on promoting the fruit of research institutions to business transformation.
