3.2 Reliability and validity test of scale
According to the related research results of Marco (2010) and Krackhardt (2002), the measuring process system, and method of simmelian ties, we can ensure the scale of simmelian ties. The simmelian ties mainly include the strong simmelian ties and the weak simmelian ties. This study refers to and synthesizes the results of related literatures(Cappelli,Neumark, 2001 Inkpen,Tsang, 2005), and combines the theme, context, and causal relational among variables to ensure the high-performance work practice system, knowledge fermenting, knowledge spiral scale, and related indicators system.
Firstly, Cronbach’s alpha coefficient and total correlation coefficient (CITC) are verified, at the same time, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) are performed by factor analysis and structural equation model (SEM). The results are shown in Table 2. The Table 2 of various indicators show that the scales have good reliability and validity, both EFA and CFA pass the test.
