Abstract

This study employed a quantitative research design using a survey method with three primary objectives: (1) to examine the work performance efficiency of employees in the logistics and transportation division of integrated health and beauty supplement manufacturing enterprises within local administrative organizations in Samut Sakhon Province, (2) to investigate the influence of intrinsic motivation on employees’ work performance efficiency, and (3) to analyze the impact of extrinsic motivation and the working environment on employees’ work performance efficiency. The sample consisted of 400 employees selected through non-probability purposive sampling. Data were collected via an online questionnaire with a Cronbach’s Alpha reliability coefficient of 0.956. Descriptive statistics, including frequency, percentage, mean, and standard deviation, were employed to summarize the data. Inferential analysis was conducted using multiple regression analysis (MRA) with the Enter method at the 0.05 significance level.

The findings revealed that employees generally perceived their work performance efficiency to be at a high level. Intrinsic motivation factors, particularly pride in achievement and the development of personal potential, demonstrated a statistically significant positive effect on work performance efficiency at the 0.05 level. Furthermore, extrinsic motivation factors such as compensation, welfare benefits, and a supportive work environment emphasizing health and safety also showed a statistically significant positive impact on employees’ work performance efficiency.

These results underscore the critical role of both intrinsic and extrinsic motivational factors, together with workplace environmental conditions, in enhancing logistics employees’ performance efficiency within the health and beauty supplement manufacturing sector. The study provides valuable insights for organizational leaders and local administrative policymakers in Samut Sakhon Province to design strategies that foster employee motivation and create healthier, safer, and more productive work environments.
