农民增收问题一直备受关注。基于河南省3863户农户调查数据,构建ERM模型,探究农业生产性服务对收入异质性农户的效应差异及其作用机制;结合PSM方法,规避模型内生性问题,验证农业生产性服务的增收效应机制。研究得出,施肥服务存在收入门... 农民增收问题一直备受关注。基于河南省3863户农户调查数据,构建ERM模型,探究农业生产性服务对收入异质性农户的效应差异及其作用机制;结合PSM方法,规避模型内生性问题,验证农业生产性服务的增收效应机制。研究得出,施肥服务存在收入门槛,其对高收入农户的增收效应更为凸显;相比高收入农户可自购农机,整地和收割服务对低收入农户增收效果显著,且对其工资性收入增长效应也被证实。农民增收应重点关注低收入农户发展问题,既要发展技术密集型服务,又要培育劳动密集型服务,这样才能助力农民富裕,推进乡村振兴战略目标的实现。 展开更多

How to integrate and disseminate globally distributed multi-source and heterogeneous spatial information is an open problem in integration and sharing service of geographic information. Here we propose a new service architecture suitable for integra- tion and sharing of distributed multi-source geographic information. We also propose a global virtual pyramid model, which can be applied in 3D virtual globes. In view of the difficulty of web multi-node geographic information sharing service, we propose a web multi-node service aggregation method, integrated in our autonomously developed virtual globe platform Geo- Globe and introduced in the National Platform for Common GeoSpatial Information Services named "T1ANDITU". It achieves 2D and 3D integration for geographic information service. 展开更多
