Comprehensive evaluation indices were carefully selected and constructed to measure the ability of technology development from the perspective of technology commercialization. The quantitative measurement of technical interrelatedness between biotechnology and information technology was realized by adopting these indices. The typical data were sampled from the financial data of the top 10 companies marketed in NASDAQ relative to information and biology technology. The research results show that the interrelatedness between biology technology and the information technology in base and system layer was gradually enhanced in the past ten years, except for the information technology in support layer.%从技术商业化角度出发,构造了用以衡量技术发展能力的综合评价指标.通过采用该指标体系,实现了生物技术与信息技术的技术关联度的定量测量,典型样本数据取自NASDAQ信息技术与生物技术行业内排名前10名公司1999～2009年的财务数据.研究表明,除了信息技术中的支撑层技术与生物技术关联度呈现出不规则变化之外,信息技术中的基础层技术、系统层技术与生物技术关联度均保持较稳定的增长趋势.
