扩大中尼两国贸易范围不仅有利于扩大两国的当期贸易规模，而且利于促进两国国内经济产业的发展，实现两国贸易可持续发展。根据比较优势原理，尼泊尔具有相对比较优势的产品出口到中国市场，可以与中国产品形成优势互补，提高两国的整体效益水平。尼泊尔企业可以依据中国市场的需求及消费者喜好，并结合本国产品特点，生产并出口到中国更多受欢迎的产品。而中国外贸企业也可以扩大对外直接投资范围，寻找新的贸易增长点。

Expanding the scope of trade between China and Nepal is not only conducive to expanding the current trade scale of the two countries, but also conducive to promoting the development of domestic economy and industries of the two countries and realizing the sustainable development of bilateral trade. According to the principle of comparative advantage, Nepal's products with comparative advantage are exported to the Chinese market, which can form complementary advantages with Chinese products and improve the overall benefit level of the two countries. Nepalese enterprises can produce and export more popular products to China according to the needs of the Chinese market and consumer preferences and in combination with the characteristics of domestic products. Chinese foreign trade enterprises can also expand the scope of foreign direct investment and look for new trade growth points.
