文章第四部分是基于在线平台的发卖和回收模式，推导了4种发卖模式和回收模式的最佳决策，详细先容了4种发卖模式和回收模式的决策顺序与推导过程。
The fourth part of the article is based on the sales and recycling modes of the online platform, deduces the optimal decision-making of the four sales modes and recycling modes, and introduces the decision sequence and derivation process of the four sales modes and recycling modes in detail.
1
S−R
在批发模式和委托回收模式（S-R）下，正向渠道和反向渠道都因此厂商为龙头的Stackelberg博弈，从属于发卖平台和采集平台。
Under the wholesale model and the entrusted recovery model (S-R), the forward channel and the reverse channel are both the Stackelberg game with the manufacturer as the leader, subordinate to the sales platform and the collection platform.
决策顺序如下：在正向渠道中，厂家首先决定批发价w，然后由发卖平台给动身卖价格p和发卖做事水平。在反向渠道中，领先厂家首先从网络平台设置废物的单价tr，然后在网络平台设置回收价格pr和回收做事水平sr。
The decision-making sequence is as follows: in the forward channel, the manufacturer first decides the wholesale price w, and then the sales platform gives the sales price p and the sales service level. In the reverse channel, leading manufacturers first set the unit price tr of waste from the collection platform, and then set the recycling price pr and recycling service level sr on the collection platform.
推导过程如下：
The derivation process is as follows:
2
M−R
直销模式和委托回收模式（M-R），因此发卖平台为主导的Stackelberg博弈。作者用京东作为例子，所有与京东做生意的制造商都须要遵守京东的规则。
The direct selling model and the entrusted recycling model (M-R) are Stackelberg games dominated by the sales platform. The author uses JD.com as an example, all manufacturers doing business with JD.com need to follow JD.com's rules.
决策顺序如下：在正向渠道中，发卖平台先决定s，然后由制造商决定p。在反向渠道中，领先的制造商首先为废物设置tr，然后由网络平台设置pr和sr。
The decision sequence is as follows: In the forward channel, the sales platform decides s first, and then the manufacturer decides p. In the reverse channel, the leading manufacturer first sets the tr for the waste, then the pr and sr are set by the collection platform.
推导过程如下：
The derivation process is as follows:

S−M
在批发模式和直接管受接收模式（S-M）下，领先的制造商和从属的发卖平台构成了 Stackelberg 博弈。反向渠道也是与紧张制造商的Stackelberg 博弈，其次是网络平台。作者以爱回收和回收宝作为例子。消费者通过爱回收二手手机时，首先在平台上提交二手手机信息，然后收到回收价格，根据提交的信息确定。消费者接管回收价格后，平台供应一系列回收做事，如二手手机邮寄、检测等做事。
Under the wholesale model and the direct recycling model (S-M), the leading manufacturers and subordinate sales platforms constitute the Stackelberg game. Backchannel is also a Stackelberg game with major manufacturers, followed by collection platforms. The author uses Aihuishou and Huishoubao as examples. When consumers recycle second-hand mobile phones through Love, they first submit second-hand mobile phone information on the platform, and then receive the recycling price, which is determined according to the submitted information. After consumers accept the recycling price, the platform provides a series of recycling services, such as second-hand mobile phone mailing, testing and other services.
决策顺序如下：在正向渠道中，制造商首先决定w。然后由发卖平台决定p和s。在反向渠道中，制造商首先决定pr，然后采集平台选择做事水平sr。
The decision sequence is as follows: In the forward channel, the manufacturer decides w first. Then it is up to the sales platform to decide p and s. In the reverse channel, the manufacturer first decides the pr, and then the acquisition platform chooses the service level sr.
推导过程如下：
The derivation process is as follows:
4
M−M
在直销模式和直接管受接收模式（M-M）下，制造商利用发卖平台和网络平台直接发卖新产品和回收废品。在这种模式下，发卖平台在正向渠道主导ECLSC，而制造商在反向渠道主导ECLSC。
Under the direct selling model and the direct recycling model (M-M), manufacturers use sales platforms and collection platforms to directly sell new products and recycle waste. In this model, the sales platform dominates the ECLSC in the forward channel, while the manufacturer dominates the ECLSC in the reverse channel.
决策顺序如下：在正向渠道中，发卖平台首先决定s，然后制造商选择p。 在反向渠道中，厂家先决定pr，然后采集平台选择sr。
The decision sequence is as follows: In the forward channel, the sales platform first decides s, and then the manufacturer chooses p. In the reverse channel, the manufacturer first decides the pr, and then the collection platform chooses the sr.
推导过程如下：
The derivation process is as follows:
4种发卖和回收办法的最佳决策如下：
The best decisions for the 4 ways to sell and recycle are as follows:
