人口老化在近幾年已經成為一個國際趨勢，並且是人力資源管理領域中的一個重要議題，台灣在接下來的一、二十年中，也將會遭遇到許多工作人口老化所帶來的衝擊。 為了要減輕老年化社會所帶來的壓力，必須去了解各個年齡層員工的基本差異以及如何去激勵他們的工作滿意度。 本研究主要目的是探討各種工作特性如何去影響不同年齡層員工的工作滿意度，為了消除不同行業別對於研究結果的影響，本研究針對中國鋼鐵公司維護部門中的員工進行調查，共有238份有效問卷。 研究結果顯示年輕的藍領階級員工比年長員工更重視升遷機會以及與同事之間的和諧關係，另一方面，年長的藍領階級員工較偏好工作穩定性高的工作。 而績效型伴隨獎賞則是同時對於年輕以及年長員工的工作滿意度都有相當的影響力。 本研究所得到的結果期望能夠作為未來人力資源管理的參考。

In recent years, aging of the populations is an international trend and has become an issue for human resource management for many countries. Taiwan is a country that will encounter huge impacts from the aging workforces in the next few decades. In order to mitigate the pressure of aging society, it is crucial to understand the differences between the employees of different ages and how to motivate their job satisfaction. This research is designed to investigate the effect of job characteristics on job satisfaction among the employees of different ages. To eliminate the potential influence of types of industry and business, this study choose maintenance department of the China Steel Company (CSC) as the research samples. There are total 238 valid samples in this study. The results from the analyses show that younger blue collar employees attach more importance to the opportunity of promotion and relationship with colleague comparing to the older employees. On the other hand, older blue collar employees prefer the job with higher job security. Meanwhile, performance-contingent reward is a significant job characteristic for both younger and older employees when considering job satisfactions. These findings can be taken into consideration for the future human resource management strategy.
