【摘要】：随着传统能源的日益紧缺及其对环境造成的污染,新能源的开发与使用在全球范围内越来越被重视。发展新能源产业,不仅低碳环保,还能造就新的经济发展领域。当前中国已经把新能源产业列为国家重点发展的战略性新兴产业,给予更多的政策支持。但中国新能源产业因起步晚、技术水平低,总体水平还比较落后,因而技术效率对新能源产业的发展至关重要。本文拟测算中国新能源产业的技术效率,并对其影响因素进行实证研究。本文首先界定技术效率的内涵,并阐述技术效率的测算方法—随机前沿分析方法,分析中国新能源产业技术效率的影响因素,如企业技术研发水平、产业集聚、政府补贴、产业政策等。其次从产业规模、产业结构、产业布局等方面分析中国新能源产业的现状、存在的主要问题,比如生产成本高、核心技术欠缺、定价机制不完善、政府补贴资金利用效率低等。然后选取2003-2012年间新能源产业最具代表性的72家上市公司为样本,基于随机前沿方法,使用Frontier4.1软件对新能源产业技术效率进行测算。最后建立Tobit模型,使用Stata12.0软件对新能源产业技术效率的影响因素进行实证检验。研究结果表明,2003-2012年间,中国新能源产业的总体技术效率水平偏低,呈现先上升后下降的趋势。中国新能源产业的技术效率受企业、政府、市场等方面因素的共同影响。技术研发水平、企业管理水平和企业规模均与技术效率呈显著的正相关关系；企业所有制(国有)对技术效率呈显著负相关关系；人力资源素质、企业成立年数和企业财务风险水平对技术效率影响不显著。政府补贴、市场集中度、产业政策、产业集聚均对技术效率皇现显著的正向影响。
[Abstract]:With the increasing shortage of traditional energy and its pollution to the environment, the development and use of new energy have been paid more and more attention in the world. The development of new energy industry, not only low-carbon environmental protection, but also create a new area of economic development. At present, China has listed the new energy industry as the strategic emerging industry of national key development, giving more policy support. However, the new energy industry in China starts late, has a low level of technology and lags behind in the overall level, so the technical efficiency is very important to the development of new energy industry. This paper intends to measure the technical efficiency of China's new energy industry and make an empirical study on its influencing factors. This paper first defines the connotation of technological efficiency, and expounds the measuring method of technical efficiency-random frontier analysis method, and analyzes the factors affecting the technological efficiency of China's new energy industry, such as the level of technological research and development of enterprises, industrial agglomeration, government subsidies. Industrial policy, etc. Secondly, the paper analyzes the current situation of China's new energy industry from the aspects of industrial scale, industrial structure, industrial layout and so on. The main problems exist, such as high production cost, lack of core technology, imperfect pricing mechanism, low utilization efficiency of government subsidy funds and so on. Then the 72 listed companies in the new energy industry from 2003 to 2012 were selected as the sample. Based on the stochastic frontier method, Frontier4.1 software was used to measure the technical efficiency of the new energy industry. Finally, Tobit model is established, and Stata12.0 software is used to test the influencing factors of technical efficiency of new energy industry. The results show that the overall technical efficiency of China's new energy industry is low from 2003 to 2012, showing a trend of first rising and then decreasing. The technical efficiency of China's new energy industry is influenced by enterprises, government, market and other factors. The technology R & D level, the enterprise management level and the enterprise scale all have the remarkable positive correlation with the technical efficiency, the enterprise ownership (state-owned) has the significant negative correlation to the technical efficiency, the human resources quality, The number of years of establishment and the level of financial risk have no significant effect on technical efficiency. Government subsidies, market concentration, industrial policy and industrial agglomeration all have significant positive effects on technological efficiency.
