中文摘要：

分析了累积logistic回归模型在后发企业技术能力提升研究中的适用性，并以汽车零部件企业为例进行了实证分析．研究扩展了针对中国的中技术制造业的后发企业技术能力提升的认识，并对后发企业技术能力提升的实证分析方法进行了探讨．研究结论显示：对汽车零部件企业而言，其技术发展模式较封闭，外部知识来源的多寡并不是技术能力提高的重要方式．而内部的研究开发和正式的外部研发合作是提高技术能力的重要来源，企业规模也是影响企业能力提升的重要因素．研究表明该实证分析方法在相关研究中具有可行性．

英文摘要：

This paper establishes a cumulative logistic regression model in analyzing technological capability-upgrading of latecomer firms. We esdablishes an analytical framework of technological capability-upgrading of latecomer firms, and chooses automobile parts industry for empirical test. The results give us a more deepened understanding of the technological capability-upgrading mechanism of middle-tech manufacturing industry. The study finds that external linkages are not major factors for technological innovation capabilities in Chinese automobile parts firms whose innovation patterns are ralatively closed. Internal R＆D, external R＆D cooperation and size of firms are key factors for innovation capability-buliding.
