新时代科技创新对中国经济高质量发展的影响

基于新时代中国经济高质量发展内涵，构建指标体系并实证分析2008—2017年中国内地30个省份经济高质量发展水平差异及空间相关性，选取3种空间计量模型分析各创新指标对经济高质量发展的影响机制。结果表明：①中国经济高质量发展水平均值为0.322，中西部地区明显偏低，经济创新发展和经济开放发展指数不高是其主要原因。中国各省份经济高质量发展水平的空间正相关性显著；②全国两阶段创新势力均明显偏低，东部地区省份两阶段创新指数、创新势力和创新效率值均处于全国较优水平，而中西部省份至少在某一阶段绩效损失显著；③经济高质量发展水平与科技研发阶段创新指数呈U型曲线关系，成果转化阶段创新势力有利于高质量发展水平提升，政府支持在成果转化阶段创新指数促进高质量发展中的正向调节效应显著。

Research on the Impact of Scientific and Technological Innovation on the High-Quality Economic Development of China in the New Era

Based on the connotation of high-quality economic development in China in the new era, the index system was constructed and the difference and spatial correlation of high-quality economic development level of China's 30 provinces from 2008 to 2017 were empirically analyzed.Three spatial econometric models are selected to analyze the impact mechanism of innovation indicators onhigh-quality economic development.The results show that:①the average level of high-quality economic development in China is 0.322.The average of central and western regions was significantly lower, and the low index of economic innovation and open development was the main reason.The spatial positive correlation of high-quality economic development in China's provinces is significant;②the innovation strength in the two stages of China is obviously low.The innovation index, innovation strength and innovation efficiency of the eastern provinces in the two stages are all at the best level in China, while the performance loss of the central and western provinces is obvious at least in one certain stage; ③there is a U-shaped curve relationship between the level of high-quality economic development and the innovation index in the R&D stage of science and technology.The innovation strength in the stage of achievement transformation is conducive to the improvement of the high-quality development level.Government support has an obvious positive moderating effect on innovation index promoting high-quality developmentin the stage of achievement transformation.
