The help effect of the path and mechanism of poverty alleviation on poor households is analyzed,and the poverty alleviation model of supporting the dark tea industry in Anhua County is summarized. Based on the experience of Anhua City’s successful use of the Internet + dark tea industry to alleviate poverty,this article proposes four policy recommendations for the use of the Internet + agricultural industry model to alleviate poverty: strengthening the software and hardware infrastructure construction for the poverty alleviation model of Internet+ agricultural industry and fostering leading agricultural enterprises and cooperatives with strong ability to drive,giving play to the advantages of Internet + agricultural industry to alleviate poverty and seizing opportunities,improving the government’s capacity to use the Internet + agricultural industry poverty alleviation model and establishing targeted industry-supporting poverty alleviation system arrangements and organizational structure,and establishing a good poverty alleviation path and a close poverty alleviation benefit linkage mechanism to ensure the maximum benefits of poor households.展开更多
