Then, Prof. Cai Tuo made theoretical analysis to the concepts of "public goods" and "international public goods". He compared the fees payed by China, the US, Japan, France and India to UN and World Health Organization through data, graph and case study. He reached the conclusion on the preference of China in supplying international public goods by the "Burden level". The data shows that the total amount of international public goods provided by China is not large and grows rapidly, which indicates an inactive attitude seen from the rate of GDP burdens. The US provides the international public goods in large and stable amount, but the attitude is not active in real sense. The amount provided by Japan is high and relatively stable, indicating an active attitude. The amount of France is high and stable, also showing an active attitude. The amount of India is low and sees a small increase, reflecting a negative attitude. The period chosen is the ten years during which China experienced the most rapid development and enjoyed the greatest upgrading of international status. Through the comparative and quantitative analysis of representative countries, the effective information and basic conclusion can be achieved, namely, the total amount of international public goods provided by China is not large and grows rapidly, which indicates an inactive attitude seen from the rate of GDP burdens.
