中文摘要：

技术创新是私营企业生存和发展的关键，怎样提升自主创新能力、实现转型升级是我国私营企业面临的重要问题。基于第十次全国私营企业调查数据的实证研究发现，从政经历与企业的创新投入有负向相关关系，而参政身份与企业的创新投入有正向相关关系。同时，对于从政经历与创新投入之间的关系，企业所在行业的行政垄断程度起负向调节作用，而对于参政身份与创新投入之间的关系，企业所在行业的行政垄断程度不存在调节作用。研究结论表明，从私营企业角度来看，一旦企业获得行政保护，将容易忽视关系其长远发展的创新活动的重要性，也使政治和经济有相互勾结的风险。

英文摘要：

Technology innovation has become the key for private enterprises to survive and develop. Accordingly, improving innovation capability and making enterprises transition have become the biggest issue for Chinese private enterprises. On the basis of data from the tenth national survey of private enterprises, an empirical study found that there is a negative correlation between entrepreneur＇s political experience and innovation input while the political identity is positively related to the innovation input. Meanwhile, the industry＇s administrative monopoly degree plays a negative moderating role in the relationship between entrepreneur＇s political experience and innovation input while it has no effect in the relationship between political identity and innovation input. The study also reveals that once the private enterprise obtains administrative protection, it would easily ignore the importance of the relationship between long-term development and innovative activities and there may exist the risk of corrupt collusion between politics and economics.
