Descripción

It is a great honor to have the opportunity to publish this book. This book is mainly divided into two parts, focusing on the performance of energy companies. The first part takes coal enterprises as an example to conduct empirical analysis, exploring the relationship between variables through ridge regression. The second part mainly focuses on the performance prediction of energy enterprises, and proposes a prediction model based on XGBoost model, including textual variables. In the two parts, there is also a discussion on the situation of mixed equity reform and mixed equity ownership in enterprises. With a focus on the impact of equity ratio on enterprise performance, we want to seek a reasonable proportion among energy enterprises with multiple mixed equity to achieve better enterprise performance.
