Relative Structure on Main Influence Factors of International Trade of New Energy Materials

All domestic and foreign literatures on influence factors of international trade of new energy materials are statistically analyzed by using Meta-analysis method, and fourteen main influence factors are identified and extracted from previous research results. After that, the paper analyzes the relative structure among the fourteen factors by using interpretive structural model. The results show that export subsidy for new energy materials, import subsidy for new energy materials, insure subsidy, export drawback, export exemption, decreasing tariff for import, discount loan, import & export surety and revenue growth are superficial and direct influence factors; support fund growth, export tariff growth and import tariff growth are intermediate and indirect influence factors; interest of payment for import goods and interest of payment for export goods are essential and basic influence factors. This analysis is helpful to open out effect system and mechanism for international trade of new energy materials.
