In closed-loop supply chain systems for power battery remanufacturing, recycling and dismantling tasks will be relegated to third-party recyclers. This has significant disadvantages, inasmuch as the asymmetric exchange of information regarding the level of recycling capacity and effort after signing a contract fiscal risks to the manufacturers. The purpose of this paper is to study the “adverse selection” of recyclers and “moral hazards” hidden in their purported effort levels, based on Information Screening Models in the principal-agent theory. Our information screening model for revenue sharing will be presented, and subsequently verified using numerical simulation to demonstrate the impact of the screening contract on the expected returns of both parties. Our results show that the sharing coefficient of the remanufacturing revenue for low-capability recyclers is distorted downwards, and only truthful reporting can retain profits. High-capacity recyclers will obtain additional information while retaining profit. At the same time, as the proportion of high-capacity recyclers in the market increases, the expected return of the entrusting party increases. One critical area where this will impact the Chinese economy is in the area of new energy vehicles. We investigate a case study of our approach in new energy vehicles, which are being used to reduced CO 2 emissions, but have environmentally hazardous batteries that must be recycled safely and economically.

Based on the crash test of new energy vehicles, the mechanical response data of power batteries during the collision process were collected, and the average impact strength curve of power batteries of typical new energy vehicles in China was obtained. The average impact strength curve was mathematically processed to obtain the impact strength characteristic value and tolerance by using the equivalent trapezoidal wave and the least square method, thereby determining the test conditions of the dynamic strength of the domestic new energy vehicle power battery. The differences are analyzed by comparing with ISO 12405-3 test conditions, which provides an important reference for the revision of power battery test standards in the future.

To face the reality of resources exhaustion, the significance of recycling and remanufacturing in the closed-loop chain has become quite evident. This paper constructs a competitive recycling and remanufacturing model of the closed-loop supply chain through a case study of Midea Corp. and Gree Corp. and explores the impact of two recycling modes on total revenue of the supply chain and market share. The simulation results show that the total revenue of the supply chain will benefit from the increasing coverage points by the third party and the increasing environmental awareness of certain regions. The retailers show more enthusiasm of recycling through certain amendment of the contract between manufacturers and retailers. The time of payment could be shortened in closed loop. Moreover, the improvement of recycling mechanism of the retailers can enlarge the share of supply chain market. Guiding role of the proposed model and the simulation results played in establishing a better supply chain mode is presented.

Abstract With the rapid development of new energy vehicles (NEVs), the recycling and reuse of retired power batteries has attracted extensive attention from the society and scholars. In this paper, we establish a closed-loop supply chain model composed of the government, one power battery supplier and one NEV manufacturer. Based on game theory, considering whether the battery supplier encroaches on the power battery recycling channel, we study the optimal decisions of the government and supply chain members under different government subsidy policies (no subsidy, subsidy for the NEV manufacturer and subsidy for consumers) and their impact on profits and social welfare. The results show that, whether the battery supplier encroaches on the recycling channel or not, compared with the no subsidy policy, subsidy for the NEV manufacturer is more conducive to the improvement of enterprise profits and social welfare. In addition, whether the battery collection quantity is constrained by the NEV sales quantity, when the recycling channel cost is lower than a certain threshold, the encroachment is always beneficial to the battery supplier. When the recycling channel cost is within a certain threshold range, the encroachment will achieve a win–win situation; otherwise, win–lose. When the recycling channel cost is higher than a certain threshold, the encroachment behavior has no impact on the NEV manufacturer and the battery supplier. Finally, we investigate the impact of key parameters on the enterprise profits and social welfare through numerical experiments. We also find that the environmental awareness of consumers have significant impacts on social welfare.

In recent years, in order to promote the independent development of the new energy vehicle industry, Chinese government has decided to reduce the consumption subsidies for new energy vehicles until the subsidies are completely withdrawn. The reduction of consumption subsidy has a great impact on the production and sales of new energy vehicles in the whole vehicle market. However, does the reduction of this subsidy also have an impact on other enterprises in the new energy vehicles industry chain? This paper tests this problem using data from 2016 to 2018, and finds, through empirical analysis, that during the period of subsidy decline, the profitability of component enterprises is significantly positively correlated with this subsidies, while the r&d investment of enterprises is significantly negatively correlated with this subsidies. The results show that in terms of profitability, the reduction of consumer subsidies not only has an impact on the whole vehicle industry of new energy vehicles, but also has an adverse impact on the core component companies in the industrial chain. However, in terms of r&d, the reduction of subsidies has more negatively strengthened the input and attention of R&D in component companies.
