信息技术投资是否提高了工业上市公司的技术效率?

Whether the Information Investment can Improve the Technology Efficiency of Industrial Listing Corporation

本文分析了我国工业上市公司2000～2012年间信息技术投资对其技术效率的影响。采用面板随机前沿（PSFA ）模型，通过超越对数生产函数，计算了上市公司的技术效率，并用面板数据模型分析了信息技术投资等因素对技术效率的影响。结果发现信息技术投资并没有给工业上市公司带来效率提升，而企业公司治理、规模、行业、地域等因素却对技术效率具有显著的影响。这说明我国工业上市公司可能存在信息技术投资过度，或者没有通过有效地管理发挥其作用。因此，在微观层面上，信息化与工业化融合并不是不断增加信息技术投资，而是要提高管理水平，充分发挥信息技术投资的作用。

This paper analyzes the impact of information technology investments on its technical efficiency of China＆#39;s Industrial List-ing Corporation between 2000 and 2012 . The panel Stochastic Frontier （PSFA） models and the translog production function , are used to calculated the technical efficiency of listing corporation . Moreover , it analyzed the influence factors of information technology investment on technical efficiency by Panel Data model . Results indicate that information technology investment are not to enhance the efficiency of Indus-trial Listing Corporation . However , enterprise governance , scale , industry , regional and other factors can significantly affect the efficien-cy of technology . This shows that China＆#39;s Industrial Listing Corporation may be excessive investment in information technology , or did not play its role through effective management . Therefore , at the micro level , the integration of informatization and industrialization is not in-creasing investment in information technology , but to improve the management level , give full play to the role of information technology in-vestment .
