摘要
创新是提高综合国力的战略支撑,探索提升创新能力的影响因素十分重要。2017年的《政府工作报告》首次提及数字经济,数字经济成为中国经济发展的重要方向,其对创新的影响值得探究。本文从数字经济与创新的视角,借助2015年中国287个地级市的截面数据,构建了城市数字经济发展水平评价体系,并采用OLS+稳健标准误方法对数字经济是否促进了区域创新能力进行了回归估计。研究发现,数字经济发展能够促进创新能力的提升。同时,数字经济发展对技术含量最高的发明创新影响最大,对外观设计创新的影响次之,这说明数字经济发展驱动的是真正的创新,而非模仿式创新。在此基础上,文章又分别作了区域比较以及数字经济不同发展水平对创新增长的影响估计,发现东北地区的数字经济对创新的影响作用最大,东部地区则最弱;并且,数字经济发展水平对创新的影响呈非线性关系,数字经济发展水平低的区域推动创新的作用更大,但主要影响的是外观设计创新,而数字经济发展水平高的区域则主要影响发明创新。最后,文章就如何通过数字经济促进区域创新能力提升提出了相关政策建议。
Independent innovation is a strategic groundwork of improving comprehensive national power. It is important to explore the driving factors of independent innovation capabilities. In 2017,the term digital economy appeared in Report on the Work of the Government for the first time. Digital economy is one of future directions of developing Chinese economy. It is worthwhile to study the impact of digital economy on independent innovation. Based on 287 cross-sectional city data in 2015,the paper first set up a framework to evaluate the city-level of digital economy,and then investigated the impact of digital economy on independent innovation in China with OLS plus robust standard error method. The findings showed that digital economy reinforced the capability of independent innovation. Digital economy had the biggest effect on invention innovation,and design innovation next,which reflected that digital economy contributed to genuinely independent innovation rather than imitative innovation. Then a regional comparison was made. The findings showed that digital economy had the biggest impact on innovation in northeastern region,with the least impact in eastern region. However,digital economy with the lowest level affected design patent mostly whereas high-level digital economy affected invention patent mostly. Finally,the paper proposed several suggestions for developing independent innovation.
