Due to such serious problems as environmental pollution, rising prices and the shortage of oil resources, the government has introduced a series of related policies like restrictions on fuel vehicles. Compared with fuel vehicles, electric vehicles with less pollution and lower energy consumption have drawn wide attention from people of all walks of life. For long-term and sustainable development, enterprises use limited distribution resources to obtain greater profits, and integrate customer classification and mixed models into vehicle routing problems. Under the driving restriction policy, and according to the multi-attribute characteristics of customers, the entropy method is used to assign index weights and reclustering to classify customers, and build a vehicle routing optimization model based on customer classification and mixed vehicle models, aiming at the minimum fixed cost, penalty cost and transportation cost. Then, for this problem, a genetic algorithm is used to solve the model. With a case study of a logistics company in Hangzhou, a comparative analysis is carried out under different schemes to verify the validity of the model.
By constructing the policy-making models of retailers and manufacturers under different money-back guarantees, the money-back guarantee policy-making of retailers in introducing store brands is studied. And by comparing the equilibrium solutions of retailers in different cases, the influence of retailer’s money-back guarantee strategy on the optimal pricing decision is discussed. The research shows that when the store brand does not provide a money-back guarantee and the national brand satisfaction is less, providing a money-back guarantee for the national brand is beneficial to retailers and manufacturers, otherwise it is always beneficial for retailers to provide money-back guarantee for both products. On the other hand, when the national brand does not provide a money-back guarantee, it is always beneficial for the manufacturer to provide a money-back guarantee for the store brand, otherwise it is beneficial for both manufacturers and retailers to provide a money-back guarantee for the store brand within a certain range.
By calculating the value chain status of service outsourcing industry in 34 economies, and by using the international property right index（IPRI） and its subdivisions published by the International Property Right Alliance（IPRA） from 2008 to 2020, a grey comprehensive correlation analysis is made on the property right system and classification index of each economy and its value chain status of service outsourcing industry. The results show that the relationship between property right system and value chain status of service outsourcing industry is very close, and the average grey comprehensive correlation between the two in developed economies is generally higher than that in developing countries and emerging economies. Through further decomposing property right index, it is found that China’s rule of law, political stability, property registration and service outsourcing industry value chain status have a higher grey comprehensive correlation, but the correlation of intellectual property protection and loan convenience is obviously lagging behind other countries or regions. This study provides a new way for the transformation and upgrading of China’s service outsourcing industry under the new normal for the first time from the perspective of improving the property rights systems.
The enterprise digital transformation are measured through text mining, and the influence and mechanism of digital transformation are empirically tested on enterprise growth capacity. It is found that digital transformation can significantly improve the growth capacity of enterprises. Heterogeneity test results show that digital transformation has a significant positive driving effect on the growth capacity of both state-owned enterprises and non-state-owned enterprises, and a more prominent effect on the former. Besides, it has a significant positive effect on the growth capacity of enterprises in east-central region rather than in western region. From the perspective of mechanism test, enterprise digital transformation can promote enterprise’s growth ability by improving enterprise innovation ability, reducing enterprise debt and management cost. Therefore, in order to enhance the promotion effect of digital level on enterprise growth capacity, Chinese enterprises should strive to realize the transformation and upgrading of digital industry, integrate digital transformation into production and research and development links, and improve innovation capacity to a great extent.
The current refrigerated fresh storage P2P sharing in China’s rural areas is faced with three difficulties: difficulty in distinguishing true or false supply and demand information and the low efficiency in matching them, difficulty in sharing information of refrigerated fresh storage records which are likely to be tampered, and the difficulty in determining the responsibility for loss in the settlement of transactions. In response to the difficulties, and by combining the transparency and distributed characteristics of blockchain technology, a blockchain-based P2P sharing platform system is established for refrigerated fresh storage of agricultural products. A blockchain-based P2P sharing framework is constructed according to the characteristics of supply and demand of refrigerated warehouses in rural areas; The supply and demand matching mechanism, multi-object information sharing mechanism and automatic settlement mechanism of transactions for the refrigerated fresh storage of agricultural products are designed under the blockchain framework; A prototype system of the platform is developed by the Hyperledger Fabric framework. The platform can realize efficient matching and credible transactions between the scattered and diverse agricultural storage resources and storage demands in rural areas of China, ensure the integrity of the cold chain in the storage of fresh agricultural products, protect the legitimate rights and interests of all parties to the transaction, and provide a new idea for a safe and reliable P2P refrigerated warehouses sharing platform.
