区域创新环境是否提高了中国信息技术产业创新效率——基于两阶段创新过程的实证研究

信息技术产业创新过程与一般高新技术产业相比有其特殊之处，且创新环境在不同创新阶段影响不同，然而既有文献对此关注较少。将创新过程分解为技术研发和市场转化两个阶段，运用面板随机前沿模型测度了2011—2016年中国各省份及经济区域信息技术产业创新效率，并实证检验了创新环境对创新效率的影响。研究发现：中国信息技术产业创新效率在两阶段均处于较低水平，且都具有明显的时间趋势，技术研发阶段效率逐年递减，市场转化阶段效率逐年递增；区域产业规模对技术研发阶段效率影响不显著，但对市场转化阶段效率影响非常显著，呈倒U型关系；区域研发资源和区域研发环境正向影响技术研发阶段效率；区域经济资源对市场转化阶段效率有显著正向影响；区域市场环境对市场转化阶段效率影响不显著；创新环境整体上促进了大部分经济区域技术研发阶段创新效率，但没有促进东部沿海和黄河中游地区创新效率；创新环境整体上促进了中国各经济区域的市场转化效率。

Does the Regional Innovation Environment Improve the Innovation Efficiency of China's Information Technology Industry

Compared with the general high-tech industries, the innovation process of the information technology industry has its special features, and the impact of the innovation environment is different in different innovation stages.The innovation process is decomposed into two stages:technology research and development and market transformation.The panel stochastic frontier model is used to measure the innovation efficiency of information technology industry in China's provinces and economic regions from 2011 to 2016, and the impact of innovation environment on innovation efficiency is empirically tested.It is found that the innovation efficiency of China's information technology industry is at a low level in both stages, with great room for improvement.Moreover, the innovation efficiency of the two stages has obvious time trend, the efficiency of technology research and development stage decreases year by year, and the efficiency of market transformation stage increases year by year.Regional industrial scale has no significant influence on the efficiency of technology research and development stage, but it has a significant influence on the efficiency of market transformation stage, and there is a significant inverted u-shaped relationship.Regional R&D resources and regional R&D environment positively affect the efficiency of technology R&D stage; Regional economic resources have a significant positive impact on the efficiency of market transformation stage.Regional market environment has no significant influence on the efficiency of market transformation stage.In general, the regional innovation environment has a significant positive impact on the efficiency of the information technology industry in both stages, especially in the market transformation stage.
