本文运用规模报酬可变的DEA模型测度2000-2007年中国省域科技创新效率并分析其收敛性和影响因素。研究发现:科技创新效率具周期性波动演化特点;东部省域科技创新效率高于中西部省域,西部省域科技创新效率提高快,赶上并超过了中部省域;西部省域科技创新效率具有绝对和条件收敛特征;全国和东中部省域科技创新效率条件收敛显著,绝对收敛特征不明显;考察期内工业结构、对外开放度、高等教育发展水平对科技创新效率具有正影响效应,而政府影响力具有负向作用。研究结果为国家及地区科技创新效率政策提供参考信息。
Abstract
Based on the panel data of China’s provinces during the period of 2000-2007, an empirical analysis on the scientific and technology innovation efficiency and its convergence and influence factors is conducted by using the Data Envolopment Analysis(DEA) model of variable scale returns. The results are as follows:the scientific and technology innovation efficiency has the character of periodic undulation evolution; the east provinces have higher innovation efficiency than that for the middle and west provinces, the efficiency for west provinces enhances quickly, has caught up with and surpassed the efficiency for middle provinces; the west provinces have the absolute and conditional convergence; the conditional convergence of the whole country and the east-middle area is remarkable, however, the absolute convergence is not obvious; the industry structure, the openness, and the higher education level of development have the positive influence on the efficiency, meanwhile the government effect has the negative impact on scientific and technology innovation efficiency. The conclusions will provide enlightenments for the policy of national scientific and technology innovation efficiency.
