“一带一路”背景下对外开放与经济增长效应研究——基于内陆节点城市的经验实证

Study on the Effect of Opening to the outside world and Economic Growth under the Background of“Belt and Road”——Empirical Evidence based on the Inland Node Cities

改革开放40年,中国经济年均增长约9.5%,持续快速的增长创造了“中国奇迹”,而这一经济增长的成绩与中国的对外开放密不可分。“一带一路”建设是对新时期中国全面深化改革、对外开放的深入推进,承担着激活内陆地区经济活力,打造海陆内外联、东西双向开放的全方位对外开放格局的使命。所以,以“一带一路”背景下内陆节点城市为研究样本,利用2002—2017年“一带一路”的7个内陆节点城市重庆、成都、郑州、武汉、长沙、南昌、合肥为样本,基于CD生产函数,引入时间虚拟变量进行实证检验,发现“一带一路”建设的深入实施能给地区经济带来显著的正向溢出效应。

In the 40 years of reform and opening up,the average annual growth of China’s economy is about 9.5%,and the sustained and rapid growth has created the“Chinese miracle”,and the achievements of this economic growth are inseparable from China’s opening to the outside world.The construction of“Belt and Road”is an in-depth promotion of China’s comprehensive deepening of reform and opening to the outside world in the new period,and undertakes the mission of activating the economic vitality of the inland areas and creating a comprehensive pattern of opening to the outside world with the combination of sea and land,and the two-way opening between east and west.Therefore,taking the inland node city under the background of“Belt and Road”as the research sample,using Chongqing,Chengdu,Zhengzhou,Wuhan,Changsha,Nanchang,Hefei as the sample of seven inland node cities of“Belt and Road”from 2002 to 2017,based on the CD production function,the time virtual variable is introduced to carry on the empirical test,and it is found that the deep implementation of“Belt and Road”construction can bring significant positive spillover effect to the regional economy.
