Table 2

Summary of parameters.

Parameters	Description
Network freight platform (strict supervision, loose supervision)	Total revenue of network freight platforms:
	Additional supervision costs are incurred when network freight platforms adopt strict supervision strategies
	If freight carriers provide low-quality services and receive complaints from freight shippers, when the network freight platform adopts a strict supervision strategy, the penalty for freight carriers is . When the network freight platform adopts a loose supervision strategy, the penalty for the freight carriers is , . For the convenience of calculations, let
	If freight carriers provide low-quality services and receive complaints from freight shippers, the compensation amount paid by the network freight platform to the freight shippers is
	If the platform discovers private transactions occurring between freight carriers and freight shippers, when the network freight platform adopts a strict supervision strategy, the penalty for freight carriers is . When the network freight platform adopts a loose supervision strategy, the penalty for the freight carriers is . For the convenience of calculations, let
	The loss caused to the network freight platform due to freight shipper jump dealing is
Freight carriers (high-quality services, low-quality services)	The total revenue of freight carriers, when they enter the network freight platform and receive task assignments, is
	The additional cost of providing high-quality service by freight carriers, such as the cost of quick-response customer service and on-time delivery, is and ; otherwise, freight carriers have no motivation to save such costs
	The total cost of offline services for freight carriers is ,
Freight shippers (nonjump dealing, jump dealing)	The total revenue earned by freight shippers due to meeting logistics needs is
	The additional cost added to the shipper when freight carriers provide low-quality services, such as loss of stock or increased storage costs, is
	The total online service fee paid by the freight shipper to the network freight platform is
	When the freight shipper engages in private transactions with freight carriers, the fee paid by the freight shipper is , which is also equal to the total revenue of the freight carrier in this situation
