中文摘要：

企业孵化器对新创企业的发展有积极作用，得到了政策制定者、金融家、企业家的认同。孵化器的支持者认为，被孵化企业的可持续化高增长率和存活率是孵化模式成功的证据。然而在以往研究中，很少人从孵化器为什么能够成功的角度进行研究。本文从三个理论着手解释孵化器的成功。用来自于西安高新技术产业开发区的调查数据和bootstrap回归技术。论证了孵化器增强了新创企业的社会资本和正统性命题，而资源整合理论得不到支持。

英文摘要：

Business incubators have established themselves as a recognized method of developing emerging firms that is popular with policy-makers, financiers, and the business press. Proponents of incubation point to the substantially higher rates of growth and firm survival among incubated firms as evidence of the viability of the incubator model. Within the incubator literature, however, the question of why incubators succeed is rarely addressed. We draw on three theoretical perspectives to assess incubator success. Using a sample obtained from XDZ and bootstrap regression techniques, we find support for the proposition that incubation enhances the social capital and legitimacy of tenant firms.
