A Study on Ultra Circulation Theory of Agricultural Technology Innovation Chain and Its Mechanism

The circulation of agricultural technology innovation chain refers to the process started by some basic constitutive link, passed through other links in order, and returned to the initial one, It contains response circulation, catalytic circulation and ultra circulation three levels. Its mechanism of circulation is that every link of the response circulation in the same agricultural technology innovation chain pushes the catalytic circulation of the same or the similar link in the same or different agricultural technology innovation chain, and the catalytic circulation works on the ultra circulation in the same way. The ultra circulation of agricultural technology innovation and agricultural technology initial commercialization, makes them coupled as par agenesis. Through the ultra circulation of agricultural technology initial commercialization and the proliferation of agricultural technology, one circulation of it could be realized and completed. Through the ultra circulation of the proliferation of agricultural technology and the innovation of agricultural technology, the whole agricultural technology innovation chain could start to circulate with new demand, such circulations go on.
