“一带一路”倡议与区域对外开放度时空演化

“The Belt and Road” Initiative and the Spatial-temporal Evolution of Regional Openness

"一带一路"是新时期中国对外开放战略的统领,正在对各省对外开放格局产生重大影响。利用2010—2017年甘肃各市(州)对外贸易、实际利用外资与国际旅游外汇收入数据,首先测算对外开放度,并刻画甘肃各市(州)对外开放的空间分布,其次分析各区域对外开放的空间相关关系,最后运用地理探测器模型分析甘肃对外开放的驱动机制。得到以下结论:(1)以"一带一路"倡议提出年为转折点,2010年至2017年甘肃平均对外开放度呈"下降-上升"趋势;(2)甘肃对外开放度由高至低的区域数量呈"金字塔"状分布;(3)甘肃对外开放空间格局为"西高、东低、中平衡";(4)甘肃各市(州)对外开放发展相对独立,"一带一路"倡议提出后,出现部分区域集聚现象,高度开放型区域产生空间锁定效应;(5)影响甘肃对外开放发展的主要因素有经济发展水平、城市吸引力、对外开放便利程度与第二产业规模。

'The Belt and Road'initiative has a great influence on the opening pattern of China and all the provinces in China.This paper discusses foreign trade,foreign investment and international tourism,foreign exchange income data,the opening degree of foreign exchange in Gansu from 2010 to 2016,and analyses the spatial distribution of opening to the outside world,the spatial correlation of each region’s opening to the outside world,and the driving mechanism by using the geographic detector model.The conclusions are:1)Its average opening degree shows a'decline-rising'trend;2)Its distribution pattern of opening to the outside world from high to low is'Pyramid';3)Its spatial pattern of opening up to the outside world is'west high,east low and middle balance';4)Its development of the opening of the region is relatively independent.After the implementation of'the Belt and Road'initiative,there are some regional agglomeration phenomena;5)The main factors affecting its development of opening to the outside world are the level of economic development,the urban attraction,the convenience of opening to the outside world,and the scale of the second industry.
