中国“一带一路”省市区域创新效率及空间效应

An Analysis of Provincial Innovation Efficiency and Spatial Effects in China “B&R”

以2005-2013年"一带一路"18个省、市、自治区面板数据作为研究样本,第一阶段利用随机前沿方法测算了各省、市、自治区每年的创新效率,第二阶段将第一阶段的创新效率加入生产函数模型考察创新效率及各因素对经济增长的空间效应。研究表明:21世纪海上丝绸之路省市的创新效率较高;空间滞后模型的固定效应模型较优且空间回归系数皆大于零,表明经济增长具有空间溢出效应,且创新效率的空间溢出效应最大;其中空间固定效应模型的间接效应大于直接效应,说明某一区域创新效率的变化会随时间潜在地影响其他区域的经济增长。"一带一路"战略的实施将展示"路域"经济发展特点,以创新为驱动力,着力提高沿路地区创新实力,对带动全国,甚至中亚、南亚、西亚等地区经济发展有重要战略意义。

The panel data of 18 ＂B＆R＂provinces in 2005- 2013 is used as the research sample. The first stage by using stochastic frontier approach estimates the innovation efficiency of various provinces and cities each year,the second phase uses the innovation efficiency in production function model to investigate the spatial effect of innovation efficient to economic growth. Research shows that： the 21st- Century Maritime Silk Road provincial innovation efficiency is higher; SLM fixed effects model is optimal and rho is greater than zero,shows that economic growth has spatial spillover effect. Innovation efficiency is the largest spillover effect;SLM space fixed effect model shows that direct effect and indirect effect on regional innovation efficiency change over time potentially affect economic growth in other regions. ＂B＆R＂has the characteristics of ＂expressway＂economic development that can enhance regional innovation capability by innovation. It is very significant for the development of economic of China,even Central Asia,South Asia,West Asia and other regions.
