A Study on 'Internet +' Eco-production and Eco-tourism Mode for Agricultural Enterprises

'Internet +' eco-production and eco-tourism carried out by agricultural enterprises is one of ways to increase income.Urban economic development index evaluation value（u1）,agricultural enterprises’ eco-production and eco-tourism index evaluation value（u2） and Internet popularity index evaluation value（u3） constitute the ternary coupling system.The ternary coupling coordination degree（D3） combined with u2 can be used to judge whether the agricultural enterprises practise eco-production and eco-tourism mode.When u2≥ 0.5000,D3≥0.6000,the autonomous mode for agricultural enterprises can be used; when 0.4000≤u2< 0.5000,0.5000≤D3< 0.6000,the mode of cooperation with travel agency can be used; when 0.3000 ≤u2< 0.4000,0.4000 ≤D < 0.5000,the tourism business transfer mode can be used; when u2< 0.3000,D < 0.4000,the tourism business should not be carried out.All the above four modes require 'Internet +'.
