In recent years, researchers’ research on government credibility has mostly focused on exploring theories and mechanisms, with little empirical research on this topic. This article intends to apply variable selection models in the field of social statistics to the issue of government credibility, in order to achieve empirical research on government credibility and explore its core influencing factors from a statistical perspective. Specifically, this article intends to use four regression-analysis-based methods and three random-forest-based methods to study the influencing factors of government credibility in various provinces in China, and compare the performance of these seven variable selection methods in different dimensions. The research results show that there are certain differences in simplicity, accuracy, and variable importance ranking among different variable selection methods, which present different importance in the study of government credibility issues. This study provides a methodological reference for variable selection models in the field of social science research, and also offers a multidimensional comparative perspective for analyzing the influencing factors of government credibility.展开更多

A Structural Equation Model (SEM) is developed for the implementation of CE, then the model is applied to the following Jordanian industrial sectors: chemical and cosmetics industries, engineering and electrical industries and information technology, wood and furniture industries, and construction industry. The implementation level for the six CE practices among the selected sectors is investigated;a statistical comparative analysis between the considered industrial sectors is conducted. Thereafter, a system dynamics model is developed to understand the true CE trade-offs, which is used as a validity measure to insure that the proposed statistical model and hypotheses are valid.展开更多
