    Abstract: In 2016, transport emissions (mainly involving roads, railways, aviation and maritime transport) accounted for more than 24% of global carbon dioxide emissions. It is also expected to grow faster than any other sector, which poses a major challenge to efforts to reduce emissions in accordance with the Paris Agreement and other global goals. Each year there is a remarkable growth in vehicles that emit massive amounts of greenhouse gases, which highly contribute to climate change. So, it is essential to reduce carbon emissions by changing transport. Electric cars, trucks, and buses produce no tailpipe emissions and thus help reduce local air pollution. Moreover, buses typically run on diesel fuel or compressed natural gas, emitting nitrogen oxides and sulfur dioxide that reduce air quality and are eliminated by electrification. The theme of this paper is to study the fundamental reasons and limitations of the electrification of transport. The research methods of this paper are as follows: Firstly, search relevant documents and obtain information that can use. Secondly, sort out information and then conclude. Research shows that the need for electrification of transport is because it is environmentally friendly, has lower costs for customers compared to conventional vehicles, and gives benefits to the power grid. However, several limitations that are inevitable and hard to be solved in a short period are brakes to the development of electric vehicles (EVs). Although the ultimate shift from internal combustion vehicles (ICEs) to EVs is inevitable, the market structure is fragmented, complex and emergent.

    Abstract: The aim of this study is to investigate the open problem of classification laws and results. First, a comprehensive research method of quantitative analysis-Bayesian discrimination is used to reasonably and accurately investigate the classification laws of high potassium glass and lead-barium glass, obtaining the Bayesian discriminant for high potassium glass ????1 = 2.909????1 - 0.117????2 + 4.487 ????3 + 2.432????4 + 1.097????5 + 3.352????6 + 3.403????7 + 6.303????8 + 2.669????9 + 0.897????10 + 1.882????11 - 4.543????12 + 5.002????14 - 150.381 with the lead-barium glass Bayesian discriminant ????2 = 2.447????1 - 1.195????2 + 42.807????3 + 2.117????4 + 1.0971.534????5 + 3.221????6 + 3.299????7 + 4.830????8 + 2.513????9 + 1.226????10 + 1.590????11 - 5.628????12 + 3.087????13-111.481. Then, using the clustering process-Bayesian discrimination method, the number of sample clusters was roughly determined using systematic clustering, and the data were categorized in detail using K-Means clustering, resulting in the possibility of classifying each of the high-potassium and lead-barium glasses into Three subclasses were identified, and Bayesian discriminant functions were derived for each subclass, and the data were tested to justify the subclasses.

    Abstract: Regulatory inquiries are becoming more and more common these days. In a broad sense, corporate regulation is the act of auditing, evaluating and intervening in the compliance, authenticity and legal compliance of a company's objectives and results so that the corporate governance system operates healthily. Whether a company's being regulated has various impacts, positive or negative, on performance and share price is explored using the event study method, and the number of regulatory inquiries and questions asked of the company is described in detail using Duo Rui Pharmaceuticals as a case study, with a brief summary of the company's responses. This article analyses the impact of the company's performance after the IPO, starting with operating capacity, profitability and growth capacity, and comparing the data before and after the IPO. The comparison reveals that the overall operating capacity is slightly lower than before the IPO, and the company's profitability also shows a decline and a significant decline in growth capacity, indicating a reduction in the scale of the company's development. Regarding the correlation between regulatory enquiries and share price performance, the number of enquiries made to all GEM-listed companies under the registration system and the price suppression rate is statistically significant. It can be seen that the number of IPO enquiries directly impacts the price suppression rate of companies; the more IPO enquiries are made, the lower the price suppression rate.

    Abstract: Domestic energy consumption is the second largest source of carbon emissions in China, and it is important for residents to implement household energy-saving behaviors to reduce their domestic carbon emissions. In this context, based on questionnaire data from 436 residents in different cities of Shandong Province, structural equation modeling was used to analyze the influencing factors of residents' household energy-saving behaviors and their mechanisms of action under the framework of TPB-NAM integration theory. The results show that: (1) Personal norms, behavioral attitudes, subjective norms, and perceptual behavioral control all influence residents' household energy-saving behavior through the mediation of residents' household energy-saving behavioral intentions, with the personal norms path coefficient of 0.762 having the most significant positive effect on household energy-saving intentions. (2) Awareness of consequences is an important factor in determining the implementation of household energy-saving behavior, which can positively influence personal norms through direct or indirect effects, and thus influence residents' behavioral intentions and household energy-saving behavior. (3) Subjective norms can both directly drive residents' intentions to save energy in their homes and act as antecedent variables for behavioral attitudes and perceptual behavioral control to drive behavioral intentions to implement home energy efficiency.
