【摘要】：改革开放以来,我国经济增长主要依靠物质消耗、要素投入和低成本比较优势,但是这种发展模式已经难以持续,资源能源难以支撑,生态环境难以承受。因此,必须充分发挥“创新作为引领发展第一动力”的作用,推动传统经济增长方式向创新驱动加速转变,大幅度提高科技进步对经济增长的贡献作用,使自主创新成为经济社会又好又快发展的内在动力。甘肃省作为我国典型的西部欠发达地区的省份,科技创新资源相对丰富,近年来科技进步也相对较快。基于此,本研究在国家创新驱动的战略下,以典型地区为例,探索欠发达地区依靠科技创新推动经济增长具有重要理论价值和现实意义。本研究通过建立VAR模型和面板数据模型深入分析了科技创新对甘肃省经济增长的影响及其区域差异。首先构建测算甘肃省科技创新能力值的指标体系,使用熵值法测出1998-2014年甘肃省科技创新能力值;其次,通过检验科技创新和经济增长之间的相关性、平稳性、因果性,使用自回归模型实证分析科技创新对甘肃省经济增长的影响;再次,基于甘肃省14个地州市的面板数据分析了科技创新对甘肃省经济增长的影响;最后探讨了科技创新对甘肃省经济增长影响的区域差异。基于上述研究,本研究主要得出以下结论:(1)甘肃省科技创新能力明显提升。通过熵值法测算了1998-2014年甘肃省科技创新能力,结果显示,甘肃省科技创新水平在研究期间有明显的提高;(2)科技创新能够显著促进甘肃省经济增长。通过建立VAR模型,结果显示科技创新能够显著促进甘肃省经济增长。然后,基于甘肃省14个地州市的面板数据的分析结果同样得出科技创新对甘肃省经济增长有显著影响;(3)科技创新对甘肃省经济增长有明显的区域差异。影响程度最强的为兰州市,影响程度较强的有嘉峪关市、白银市、庆阳市、酒泉市,影响程度一般的有临夏州、定西市、甘南州、金昌市,影响程度最弱的有武威市、天水市、张掖市、平凉市,而科技创新对陇南市经济增长影响不显著;(4)科技创新对甘肃省经济增长产生显著性影响的地区具有明显的演化趋势,影响的显著性地区逐步演化为以兰州市、酒嘉地区以及天水市为主的区域。
[Abstract]:Since the reform and opening up, China's economic growth mainly depends on material consumption, factor input and low cost comparative advantage, but this mode of development has been unsustainable, resources and energy is difficult to support, ecological environment is difficult to bear. Therefore, it is necessary to give full play to the role of "innovation as the first driving force in leading development", to accelerate the transformation from traditional economic growth to innovation-driven, and to greatly enhance the contribution of scientific and technological progress to economic growth. Make independent innovation become the internal motive force of economic society good and fast development. Gansu Province is a typical underdeveloped province in the west of China, with relatively abundant scientific and technological innovation resources and relatively rapid scientific and technological progress in recent years. Based on this, this study has important theoretical value and practical significance to explore the economic growth in underdeveloped areas by relying on scientific and technological innovation under the national innovation-driven strategy, taking typical areas as an example. Through the establishment of VAR model and panel data model, this study deeply analyzes the impact of scientific and technological innovation on economic growth in Gansu Province and its regional differences. Firstly, the index system of measuring the scientific and technological innovation ability of Gansu Province is constructed, and the value of scientific and technological innovation ability of Gansu Province from 1998 to 2014 is measured by entropy method. Secondly, by testing the correlation between scientific and technological innovation and economic growth, stability, causality, using autoregressive model empirical analysis of the impact of scientific and technological innovation on economic growth in Gansu Province; Thirdly, based on the panel data of 14 prefectures in Gansu province, this paper analyzes the impact of scientific and technological innovation on the economic growth of Gansu province, and finally discusses the regional differences of the impact of scientific and technological innovation on the economic growth of Gansu province. Based on the above research, the main conclusions are as follows: (1) Gansu province's scientific and technological innovation ability is obviously improved. The scientific and technological innovation ability of Gansu Province from 1998 to 2014 is calculated by entropy method. The results show that the level of scientific and technological innovation in Gansu Province has obviously improved during the research period; (2) Science and technology innovation can significantly promote the economic growth of Gansu Province. By establishing VAR model, the results show that scientific and technological innovation can significantly promote economic growth in Gansu Province. Then, based on the panel data of 14 prefectures and cities in Gansu Province, it is also concluded that scientific and technological innovation has a significant impact on the economic growth of Gansu Province; (3) there are significant regional differences between scientific and technological innovation and economic growth in Gansu Province. The most influential cities are Lanzhou, Jiayuguan, Baiyin, Qingyang, Jiuquan, and Linxia, Dingxi, Gannan, Jinchang, and Wuwei and Tianshui. Zhangye city, Pingliang city, but scientific and technological innovation has no significant impact on economic growth in Longnan city; (4) there is an obvious evolutionary trend in the areas where scientific and technological innovation has a significant impact on the economic growth of Gansu Province, and the significant area of the impact is gradually evolving into a region dominated by Lanzhou City, Jiujia area and Tianshui City.
