公共服务动机二阶构念的再检视:反映性抑或形成性?——基于我国东中部五个城市调研证据

Review of the Two-Order Construct of Public Service Motivation:Reflective or Formative?--Evidence Based on Data from Five Cities in Eastern and Central China

构念分为反映性构念和形成性构念。关于公共服务动机是形成性构念抑或反映性构念,学术界存在部分共识,即均认为公共服务动机一阶构念是反映性构念,但对于公共服务动机二阶构念是反映性还是形成性,学界尚存在争论。研究发现,就公共服务动机而言,"一阶反映性二阶反映性构念"在结构方程模型中的预测能力与拟合度均高于"一阶反映性二阶形成性构念",我国基层公共行政背景下公共服务动机与其一阶潜在变量之间的关系的方向是从公共服务动机到一阶潜在变量,公共服务动机应该被定义为"一阶反映性二阶反映性"构念。公共管理研究者在未来研究中应认真考虑公共管理领域构念的性质以及形成性构念或反映性构念的假设对模型的影响。

A construct is a phenomenon of theoretical interest,and is divided into reflective construct and formative construct.Public service motivation is a constructive or reflective construct,and there is some consensus among the academic circles that the first order of public service motivation is reflective.But there is a debate about the nature of the two order construction.It is found that the predictive ability and the degree of fit of the"first order reflective and second order reflective"conception of public service motivation in structural equation model are higher than the"first order reflective and second order formative".The direction of the relationship between public service motivation and its first-order potential variables in the context of grassroots public administration in China is from public service motivation to first-order potential variables,and public service motivation should be defined as a"first-order reflective second-order reflective"construct.In the future,researchers in public administration should carefully consider the nature of the constructs of public management and the effect of the nature of the constructs on the model.
