Education, as a key factor in promoting human capital accumulation and social development, has a significant impact on entrepreneurs’ well-being. Based on human capital theory, status attainment theory, and social capital theory, this study utilizes cross-sectional data from the 2021 Chinese General Social Survey (CGSS) to deeply explore the mechanism of how educational attainment affects entrepreneurs’ well-being. The results show that educational level can significantly and directly enhance entrepreneurs’ well-being. Further analysis reveals that educational level influences entrepreneurs’ well-being through three mediating variables: income, perceived social status, and social interaction. Among these, income has a negative impact on entrepreneurs’ well-being, while perceived social status and social interaction have a positive impact. Additionally, the study finds significant differences in the impact of educational attainment on entrepreneurs’ well-being across different age groups, household registration status, and entrepreneurial motivations. These conclusions provide a strong basis for universities to carry out targeted entrepreneurship education and for the government to formulate refined entrepreneurship policies.

Digital platform has become an important foundation for the development of the internet economy. The potential power of internet platform not only broadens the consumption channels of the public, but also drives the transformation and upgrading of platform enterprises.

In order to solve the problem that PCB bare boards were likely to have missed detections and false detections during the small target defect detection process, a PCB bare board defect detection algorithm based on improved YOLOv7, called YOLO-BCN, was proposed. First, the BRA attention mechanism was introduced into the original YOLOv7 backbone network to achieve more flexible computing allocation and content awareness, so that the network had dynamic query-aware sparsity. Then the CARAFE upsampling operator was replaced to extract more shallow features, thereby effectively improving the detection performance of the model for small targets. Finally, the NWD loss function was introduced and combined with IoU to optimize the regression loss function and reduce the sensitivity to small target position deviations. Experimental results show that the mAP@0.5 value and mAP@0.5:0.9 value of the improved YOLOv7 are increased by 3.28% and 2.74% respectively, compared with the original model, the F1 factor is increased by 3.91%, and the detection rate is 46.84 FPS, which effectively improves the accuracy of PCB small target defect detection.

Based on bilateral trade data between China and Russia from 2010 to 2020, this study employs a trade gravity model to explore the impact of logistics performance index (LPI), information technology development index (IDI), and product quality upgrading on trade promotion, and simulate the trade potential value.
