摘　　要：以2016—2020年交通运输设备制造业A股上市公司为研究对象,采用数据包络分析法构建规模报酬可变的BCC模型与产出导向Malmquist指数模型,分析了中国39家沪深A股样本公司的创新技术效率。结果表明:企业规模与技术进步是制约交通运输设备制造业创新效率的主要因素。扩大生产规模,不断完善发展新技术是交通运输设备制造业创新能力提高的必经之路。Taking the transportation equipment manufacturing A-share listed enterprises from 2016 to 2020 as a sample,the data envelopment analysis method is used to construct the BCC model with variable returns to scale and the output oriented Malmquist index model,and the innovation technology efficiency of 39 A-share listed enterprises in Shanghai and Shenzhen is analyzed.The results show that the scale and technological progress of enterprises are the main factors restricting the innovation efficiency of transportation equipment manufacturing industry.Expanding the production scale and continuously improving and developing new technologies are the only way to improve the innovation capacity of the transportation equipment manufacturing industry.
