Huang Ying — 2025-03-04

With the enhancement of global environmental awareness and the promotion of technological innovation, the new energy vehicle market has shown a rapid growth trend. However, due to the complexity and variability of the new energy vehicle market, accurately forecasting its sales has become a challenge. In this paper, a grey Bass model based on the weakening buffer operator is proposed for the prediction of NEV sales. This model combines the advantages of the grey system theory and Bass diffusion model, and preprocesses the data through the weakening buffer operator, which improves the accuracy of the prediction. This paper first introduces the basic principle of the grey system theory and Bass diffusion model, then elaborates the construction method of the grey Bass model based on the weakening buffer operator, and verifies the effectiveness of the model through an example. The research results show that the model can better predict the sales volume of new energy vehicles, and provide a scientific basis for the decision of related enterprises.

A New Mean-Risk Quality Portfolio Optimization Model

Yueqiu Gao — 2025-03-06

This paper introduces a new mean-risk quality portfolio optimization model, grounded in uncertainty theory. It assumes that the return of assets is an uncertain variable and utilizes data estimated by experts to test the model. The approach begins by using the expected value of return and risk quality to represent the return and risk of the portfolio respectively. A new risk measure, termed “risk quality,” is introduced, leading to the establishment of the mean-risk quality portfolio optimization model. Next, to more closely align with real financial markets, the paper integrates constraints reflecting realistic financial market characteristics. These include transaction costs, financing constraints, and threshold constraints. By doing so, it establishes a mean-risk quality model with minimized risk, providing a more robust portfolio optimization framework. Finally, both the basic mean-risk-quality model and the version incorporating realistic constraints are empirically analyzed using genetic algorithms. Sensitivity tests are conducted on the robust portfolio model with minimized risk to further validate its effectiveness.

The Impact of the Carbon Border Adjustment Mechanism (CBAM) on China's New Energy Vehicle Exports to the European Union

Wang Ziyue — 2025-03-18

With the increasingly strong call for energy conservation and emission reduction on the international stage, countries and regions such as the United States, the European Union, and Japan have begun to prepare for legislation on the collection of carbon tariffs. To address climate change, the European Commission has also proposed a series of proposals. The CBAM will open up another important track for global efforts to combat climate change. The product categories initially included in the CBAM's collection scope have been revised several times during the legislative process and have finally been determined to be cement, electricity, fertilizers, steel, aluminum, and chemical products (hydrogen). The automotive industry, including new energy vehicles, power batteries, auto parts, automotive metal raw materials, and the hydrogen fuel cell vehicle industry chain, will all be affected. As a key component of new energy vehicles, the carbon emissions during the manufacturing stage of power batteries typically account for about 30% of the total emissions of new energy vehicles, which will bring new export challenges to China's automotive industry enterprises. This paper uses the input-output method to calculate the embodied carbon emissions of new energy vehicle exports based on the input-output table and export data of automotive products, providing data support for calculating the carbon tariff rate imposed on China's new energy vehicle products. Subsequently, this paper analyzes the impact of the CBAM on the export volume, market price, and social welfare of China's automotive products from both theoretical and empirical perspectives. Finally, in the face of the challenges posed by the EU carbon tariff to China's new energy vehicle industry, several forward-looking measures are proposed from two levels: the government and the automotive enterprises.

Songqin Ye — 2025-04-02

In the context of the digital economy driving China's high-quality development, the digital transformation of rural industries is of great significance for coordinated urban-rural development and rural revitalization. Various regions have actively implemented the "High-Quality Development Project for Hundreds of Counties, Thousands of Towns, and Tens of Thousands of Villages," achieving initial successes in the integration of agriculture, culture, and tourism industries as well as in rural revitalization. By constructing diversified industrial systems and establishing industrial alliances, some regions have seen significant investments in multiple agricultural and cultural tourism projects from January to October 2024, creating distinctive brands and promoting a number of enterprises to scale up and integrate into the statistical system, thereby enhancing industrial scale and standardization. However, rural digital development still faces challenges such as insufficient elements for industrial integration, lagging digital infrastructure, and inadequate empowerment of digital inclusive finance. To address these issues, local governments have built digital financial sharing platforms by improving residents' digital literacy, strengthening the integration of digital assets and finance, and fostering cooperation among financial entities, thereby supporting the digital development of rural industries. This paper analyzes the development status, mechanisms, problems, and solutions in some regions, aiming to provide references for other areas to promote rural revitalization and common prosperity.
