| 摘 要： | 为面向冰冻圈服务功能核算，采用投入产出法和ESDA分析，评估了2012-2016年间西藏自治区公路交通基础设施建设对经济增长的贡献程度，并解释作用机理，在此基础上运用GlobalMoran's I指数和Local Moran's I指数作出空间效应分析。结果表明：公路建设直接和间接创造的增加值对区域经济增长具有巨大的促进作用，在空间分布上，各地市公路建设对经济增长的贡献度在自治区范围内存在差异，但未呈现出固定的变化趋势。由于公路对经济增长巨大的溢出效应，应高度重视公路等交通基础设施建设，加大投资力度，拓展通达里程与空间分布，在冰冻圈服务功能核算中纳入交通设施建设的社会经济效益，同时充分考虑冰冻圈气候变化等因素对交通基础设施的危害影响，确保区域经济保持平稳快速增长。

| Abstract: | Combined with the input-output method and ESDA analysis,the cryosphere service function was used to calculate the contribution of the highway construction to economic growth in Tibet Autonomous Region from 2012 to 2016 and to explain the mechanisms. On this basis,Global Moran's I index and Local Moran's I index were used to make spatial effect analysis. The results show that the added value directly and indirectly created by highway construction had greatly promoted the regional economic growth. In terms of spatial distribution,the contribution degree of highway construction to economic growth had varied from place to place without a fixed changing trend. Due to the huge spillover effect of highway on economic growth,great attention should be paid to the construction of transportation infrastructure such as highways,investment should be increased, mileage and spatial distribution should be expanded,and the harmful effects of climate change and other factors on transportation infrastructure should be fully taken into account to ensure steady and rapid growth of regional economy. |
