3.3 Hypothesis Test and empirical analysis results
(1) Based on the interval number
expansion DEMATEL method, this study firstly deals with the complexity,
fuzzy and uncertain factors in the range of interval numbers, and
according to the numerical size of the center degree and the reason
degree of each variable to determine the ordering result of the
influence degree of the independent variables (influence factor) on the
target variable (dependent variable) in order to determine the direction
and degree of action of each variable (influence factor) on the
dependent variable. The relationship among the four variables of
simmelian ties, high performance
work practice system, knowledge fermenting and knowledge spiralin the
theoretical framework is transferred from the perspective of centrality
and causality. This study determines the direction and degree of
interaction among independent variables (influence factors) and
dependent variables, and distinguishes the key cause variables and
result variables. The study determines the causal relationships between
simmelian ties and high
performance work practice system, the causal relationships between high
performance work practice system and knowledge fermenting, and the
causal relationships between knowledge fermenting and knowledge spiral,
then the four variables in the theoretical framework of the mechanism of
action are determined. The centrality variable, the cause variable, and
the result variable belong to the four variables.
The interval number DEMATEL method follows the following steps
(Jinweijian,Huhanhui, 2011; Gaopeiran,Luxinyuan, 2014;Jiangqian etc.,
2016):
Step one, constructing interval number matrix.
