中文摘要：

利用我国2005~2015年新能源汽车产业上市公司面板数据,对二元技术能力调节作用下的企业技术多元化与企业绩效之间的关系进行分析。研究发现：对于具有高技术密集度的新能源汽车行业,企业绩效与技术多元化之间呈倒U型关系;核心技术能力在企业绩效和技术多元化关系之间发挥着正向调节作用;在不同高低水平的核心技术能力情况下,技术多元化对企业绩效影响的边际量不同。由此,企业采用多元化技术战略应建立在具备核心技术能力的基础上,加强其他技术的投资,形成技术间的联动与协调,共同促进企业创新绩效的提升。

英文摘要：

Using the panel data of listed companies of new energy automotive industry from 2005 to 2015,this study investigated the relationship between technological diversification,core technology competence and firm performance.Results show：（1）The new energy automotive industry has a hightech intensive degree,and the relationship between technological diversification and firm performance comes out an inverted U shaped curve;（2）The core technology competence plays a positive moderating role in the relationship between technology diversification and firm performance;（3）Marginal value of technology diversification on firm performance differentiates with the different value of core technology competence.These conclusions show that using technological diversification strategy should be based on a certain degree of firm-specific core technology competence,and then set up a linkage and coordination between technologies to promote the firm innovation performance simultaneously.
