【摘要】：本文以技术创新和技术创新效率的相关概念和理论为基础,利用我国触屏行业18家上市公司2011-2013年的数据,采用文献研究与实证研究相结合,定性研究和定量研究相结合的方法,研究我国触屏行业技术创新效率的现状和特征,总结当前我国触屏行业的现状和发展趋势,结合实证结果中体现的问题,从而提出有针对性的措施。首先是对技术创新和技术创新效率概念的简单陈述,总结了国内外学者对技术创新效率影响因素的研究成果,并根据已有研究结果,结合我国触屏行业的特点,归纳总结了影响我国触屏行业技术创新效率的因素。其次,采用三阶段数据包络分析(DEA)对我国触屏行业上市公司技术创新效率进行研究。第一阶段运用传统DEA中的BCC模型对不剔除环境和随机因素的我国触屏行业上市公司的技术创新效率进行分析,得出的结果显示我国触屏行业的技术创新效率不高,且公司之间存在较大差距。第二阶段运用相似随机前沿分析(SFA)测算环境因素对投入松弛的影响,结果可知,政府支持、企业规模及前一年净利润是影响触屏行业上市公司技术创新的重要因素,所以剔除这些因素后我国触屏行业上市公司的技术创新效率有所变化,特别是规模效率提高的幅度比较大。第三阶段使用调整后的数据,做与第一阶段相同的DEA分析,与第一阶段的结果进行比较分析。最后,根据实证结果,结合我国触屏行业的现状和未来发展趋势,提出合理利用国家政策优惠、充分了解市场情况避免盲目投入和重视管理效率等提高技术创新效率的建议。
[Abstract]:Based on the related concepts and theories of technological innovation and technological innovation efficiency, this paper uses the data of 18 listed companies in China's touch-screen industry from 2011-2013 to combine literature research with empirical research. Combining qualitative research with quantitative research, this paper studies the current situation and characteristics of the technical innovation efficiency of China's touch-screen industry, summarizes the current situation and development trend of China's touch-screen industry, and combines the problems reflected in the empirical results. The first part is a brief statement of the concept of technological innovation and technological innovation efficiency, and summarizes the research results of domestic and foreign scholars on the factors affecting the efficiency of technological innovation, and according to the existing research results. Combined with the characteristics of China's touch-screen industry, summed up the impact of China's touch-screen industry technology innovation efficiency factors. Secondly. Three stage data Envelopment Analysis (DEAA). The technical innovation efficiency of Chinese touch-screen industry listed companies is studied. In the first stage, the BCC model of traditional DEA is used to improve the technological innovation efficiency of Chinese touch-screen industry listed companies without removing the environment and random factors. Analysis. The results show that the technology innovation efficiency of China's touch-screen industry is not high, and there is a large gap between companies. The second stage uses similar stochastic frontier analysis (SFAA) to calculate the impact of environmental factors on the input relaxation. The results show that government support, enterprise size and net profit in the previous year are important factors affecting technology innovation of listed companies in touch-screen industry. So after removing these factors, the technological innovation efficiency of the listed companies in the touch-screen industry has changed, especially the scale efficiency is improved by a large margin. The third stage uses the adjusted data. Do the same DEA analysis with the first stage, and compare with the results of the first stage. Finally, according to the empirical results, combined with the current situation and future development trend of China's touch-screen industry. The paper puts forward some suggestions for improving the efficiency of technological innovation, such as making rational use of the preferential policies of the state, fully understanding the market situation, avoiding blind input and attaching importance to the efficiency of management, etc.
