Table 2. Cronbach’s Alpha Coefficients of the independent variable “Green
Product” and each observed variable

Source: Data processed in SPSS 27.0

Through testing the Cronbach’s Alpha coefficient of the independent variable
"Green Promotion" with 3 observed variables, the total correlation coefficient of this

factor was all greater than 0.3. The overall Cronbach’s Alpha coefficient of the factor =
0.831 > 0.6, and all coefficients in the Cronbach’s Alpha if Item Deleted column satisfy
< 0.831. Thus, the "Green Promotion" variable meets the reliability requirements and
all are used for EFA analysis (see Table 3).

Promotion” and observed variables

Source: Data processed in SPSS 27.0

Through testing the Cronbach’s Alpha coefficient of the independent variable
"Green Distribution" with 4 observed variables, the total correlation coefficient of the

"Green Distribution" factor was all greater than 0.3. The overall Cronbach’s Alpha
coefficient of the factor = 0.760 > 0.6, and all coefficients in the Cronbach’s Alpha if
Item Deleted column satisfy < 0.760. Thus, the "Green Distribution" variable is
reliable and all are used for EFA analysis (see Table 4).
