Market Size of Destination, Dual-Product Market and Export Product Mix of Chinese Multi-Product Firms

Whether there exists a dual-product market in China. In fact, there are obvious distribution differences between low-end products and high-end products, which are dominated by low-end products in a "pyramid" shape. This paper explores the resource allocation in multi-product firms based on the perspective of dual-products, which is an important part of achieving high-quality development of trade. This paper explores the impact of the market size of destination on the export product mix of China's multi-product firms. It is found that with the expansion of the market size of destination, China's multi-product firms will be more inclined to export and sell their core products. Furthermore, this paper explores two intermediate mechanisms: competition effect and digital effect, both of which can effectively promote the "tilt effect" of the market size of destination on the export products of multi-product firms
