According to relevant information, the difference between underwriting and distribution parking spaces is that distribution can increase more sales channels, which is beneficial to goods, while underwriting only changes hands. Underwriting agreement, the two sides establish a stable long-term business relationship, and each specific transaction is based on the underwriting agreement and a separate sales contract is concluded.

With a good market environment, manufacturers will further improve the channel construction, thus forming a virtuous circle of the market.
