Poverty has always been one of the topics concerned by governments and researchers all over the world, especially in developing countries. Remote sensing image is widely used in poverty estimation because of its large area observation, timeliness and periodicity. In this study, we explore the applicability of convolution neural network (CNN) combined with remote sensing image in regional poverty estimation. In the 2016 economic indicators estimation of Guizhou Province, China, the Pearson coefficient of per capita GDP (PCGDP) reached 0.76, which means that the image features extracted by CNN can explain the change of PCGDP of county level economic indicators up to 76%. Compared with other methods, our method still has high precision. Based on these results, we found that convolutional neural network combined with remote sensing image can be used in regional poverty estimation. 展开更多

在本文,我选起贵州改革开放30年来的几个对经济发展有作用的因素,计量分析到底是什么因素在阻碍贵州经济的发展,又是什么在推动其经济的发展。我得出的结论是:贵州的发展更多的是靠投资和农村居民消费的结果,所以反应出贵州在开放、教... 在本文,我选起贵州改革开放30年来的几个对经济发展有作用的因素,计量分析到底是什么因素在阻碍贵州经济的发展,又是什么在推动其经济的发展。我得出的结论是:贵州的发展更多的是靠投资和农村居民消费的结果,所以反应出贵州在开放、教育、资本利用、市场的建设上存在严重的时滞性。 展开更多
