在中国与世界其他地区的贸易中,由于各国实行不同的贸易关税并设定不同的贸易壁垒,国家之间存在着不对称的贸易自由化情况。本文基于GTAP模型,实证研究了不对称贸易自由化对于中国产业经济的影响。研究发现,当中国首先降低关税时,中国的经济总量和福利水平出现了下降,但是随着中国首先对非关税贸易壁垒的逐渐降低,中国的经济总量增长速度有了回升的趋势。在非关税贸易壁垒的降低在到达一个临界点后,中国的经济总量和福利水平出现迅速的增长。研究结果表明,不对称贸易自由化对中国产业经济有深远的影响。
In the trade between China and the rest of the world, as countries implement different trade tariffs and set different trade barriers, asymmetric trade liberalization exists between countries. Based on the GTAP model, this paper empirically studies the impact of asymmetric trade liberalization on China’s industrial economy. The study found that when China first lowered its tariffs, China’s economic aggregate and welfare levels declined, but as China first lowered its barriers to non-tariff trade, China’s economic aggregate growth rate has picked up. After the reduction of non-tariff barriers to trade reached a critical point, China’s total economic output and welfare levels increased rapidly. The results show that the asymmetric trade liberalization has a far-reaching impact on China’s industrial economy.
