| 摘 要： | 基于DEA和SFA模型,本文首先分析了2001-2005年间中日两国家电上市企业的市场势力效率和盈利效率这两类技术效率;其次,在构造DEA-TOBIT和Battese&Coelli(1995)SFA这两个计量模型的基础上,进一步研究了企业R&D与广告宣传这两种市场竞争策略对这两类技术效率的当期和累计影响效果。结果显示,非参数估计DEA和参数估计SFA这两个方法在中日家电企业技术效率评价方面取得了较为一致的结果;同时,所构造的DEA-TOBIT和SFA这两个计量模型也显示了在竞争性家电制造业中,R&D对企业市场势力效率和盈利效率的累积影响效果均为积极显著,但却未能证实长期内广告宣传对这两类技术效率的积极效果。

| Abstract: | Based on SFA and DEA approaches and on the sample of dozens of Chinese and Japanese household appliance listed companies during 2001 to 2005, this paper makes a comparative study on the firm's market power efficiency and profitability efficiency.Then makes an exploratory research on the effect of R &; D and advertising to the two types of firm technical efficiencies by DEA-TOBIT and Battese &; Coelli (1995) SFA models.The empirical results show that R &; D impact significantly and positively the two technical efficiencies in long-term in highly competitive household appliance industry, however the similar relation between advertising and the two technical efficiencies cannot be verified. |
