非常困惑中！

没啥区别。有时bargaining又叫double auction。

说话要负责任

更负责任的说，bargaining通常指one buyer, one seller double auction。The buyer's and the seller's values are their respective private information.

Double auction in general refers to m seller, n buyer case. So far, there is no general result about players' strategies in a m seller, n buyer double auction. The problem is so complicated that only asymptotic solutions exist.
