Mechanism of Water Transport in Domestic and International Double Circulation

The mechanism of water transport in domestic and international double circulation is studied by using method of system dynamics. The causal model reflecting the relevance of domestic and international double circulation to water transport is built from the angle of system by means of software Vensim PLE. How the water transport deals with blocking points and pain spots and helps domestic and international circulation is analyzed. The system flow diagram reflecting the interaction between water transport and economic development is formulated and simulation is conducted to do system analysis and policy simulation. The research shows that water transport and domestic and international circulation will go on promoting each other and develop together. The policy of enhancing investments in water transport, the policies on green environmental protection and balanced development are powerful driving forces to domestic and international trading.
