本研究的目的在於探討不同類型的員工參與對員工參與決策的程度影響。員工參與的類型包括建議制度，品管圈，工作生活素質方案，以及自主式管理團隊。這些參與制度的主要目的在於提升組織的生產力，品質，與員工滿意。雖然如此，不同參與類型對員工態度與組織績效的影響效果不同。本研究認為不同類型的員工參與授予員工不同程度的決策權。本研究的實證結果顯示，越高層次的員工參與授予越高程度的決策權，而低層次的參與僅給予員工有限的決策權。 This study focuses on the effects of diverse forms of employee involvement on the degree of employees’ control, included suggestion system, quality circles, quality of working life program and self-managed work team. The primary goals of these participatory programs are to increase productivity, quality, and/or to enhance employees’ satisfaction. Although these programs might lead to such benefits, diverse forms of employee involvement have different effects on attitudes and organizational performance. This study posits that diverse forms of employee involvement may delegate different degrees of decision-making power to non-employees. Our results showed that higher levels of employee involvement were associated with higher degree of influence enjoyed by non-managerial employees. However, most employee involvement programs give restricted control to non-managerial employees in personnel and production areas, but not in strategic issues.
