摘要
综合运用熵值法、空间自相关、多元线性回归、地理探测器、样带等研究方法,分析2004—2013年中国336个地级及以上行政区的经济开放度的时空演化特征及影响因素。结果表明:(1)中国城市经济开放度时空动态的差异特征显著。经济开放度水平整体有所提升,总体区域差异逐渐缩小;由东部沿海城市经济开放度高和西部内陆城市经济开放度低而形成的"东高西低"空间形态依然显著;珠三角、长三角、环渤海地区城市经济开放度较高且在空间上集聚;青藏高原地区、西北地区、云贵高原地区经济开放度较低;黄淮海地区、环渤海经济圈北部、东北地区北部沿边城市经济开放度提升较快且在空间上形成集聚;青藏高原东北部、珠三角外围以及云贵高原以南地区出现经济开放度下降较快的城市集聚区。(2)东部沿海、东北及西北部沿边、长江沿岸、陇海—兰新及宝成—成昆铁路沿线、京港澳高速公路样带城市经济外向发展路径差异明显。(3)城市经济发展水平、科研投入、国家政策、旅游配套设施、第三产业比重、投资强度、人才聚集度等是影响城市经济开放度空间分异的主导因素。
The spatial and temporal characteristics and the influencing factors of economic openness of 336 cities in China from 2004 to 2013 were analyzed systematically by using the methods including entropy evaluation,spatial autocorrelation,multiple linear regression,geography detectors and transect.Results show that overall economic openness continued to improve,overall regional difference was converged.The temporal and spatial differences of the city economic openness were significant,and the pattern of“East High and West Low”remained unchanged,which were made by the high economic openness of eastern coastal cities and the low economic openness of western inland cities.Cities of Pearl River Delta,Yangtze River Delta and Circum-Bohai Sea Economic Zone maintained high economic openness level,while the low city economic openness level was maintained in Qinghai-Tibet Plateau regions,Northwest China and Yunnan-Guizhou Plateau.Huang-Huai-Hai Region,north of Circum-Bohai Sea Economic Zone and northern border cities in Northeast China economic openness increase rapidly and formed on the space agglomeration,while the economic openness of the northeast cities of Qinghai-Tibet Plateau regions,periphery area of Pearl River Delta and cities on the south of Yunnan-Guizhou Plateau region decline fastest and formed on the space agglomeration.The city economic openness trend of transects including the eastern coastal transect,the border of northeast and northwest China transect,the Yangtze River transect,Lianyungang-Lanzhou railway and Lanzhou-Urumqi railway transects,Baoji-Chengdu railway and Chengdu-Kunming railway transects,106 National Road transect and G4 Beijing-Hong Kong-Macao Expressway transect were significantly different.There are many factors affecting city economic openness,mainly including economic development stage,input for scientific research,public policy,tour supporting facilities,the level of tertiary industries,investment intensity and human capital concentration.
