目的:探索我国省域孕产妇死亡率的空间分布特征;同时利用空间计量方法,比较不同的社会经济发展因素对孕产妇死亡率的影响。方法:通过计算Moran’s I指数测算省域孕产妇死亡率的空间相关性;并通过空间计量模型对相关变量进行空间面板检验。结果:我国省域孕产妇死亡率具有较强的空间正相关性;空间计量检验结果表明考虑空间交互效应下的地区经济与卫生资源等因素将对孕产妇死亡率产生较大的影响。结论:由于我国省域孕产妇死亡率具有较强的空间正相关性,进一步的提升区域经济发展和医疗服务水平不仅能降低区域内的死亡率水平,同时会促进相邻区域死亡率水平的降低。
OBJECTIVE: To explore the spatial distribution of maternal mortality rate in China’s provinces and to use the spatial measurement method to compare the impact of different social and economic development factors on maternal mortality. Methods: The Moran’s I index was used to calculate the spatial correlation of maternal mortality rate in the province. The spatial variables were used to test the related variables through spatial econometric model. Results: The maternal mortality rate in China’s provinces has a strong spatial positive correlation. The spatial metrological test results show that the factors such as regional economic and health resources under the spatial interaction effect will have a greater impact on the maternal mortality rate. Conclusion: Due to the strong positive spatial correlation of maternal mortality rate in our province, further improvement of regional economic development and medical services will not only reduce the level of mortality in the region, but also reduce the level of mortality in adjacent regions .
