Note: N. of items = number of items of each eco-innovation dimension; * all standardized
coefficients are positive, high and significant (sig. < 0.05).
Convergent and discriminant validity of the eco-innovation construct
The eco-innovation dimensions were tested for convergent and discrimi-
nant validity together in the eco-innovation construct structural model,
where dimensions were modeled as first-order latent constructs and cor-
related with each other (see Figure 16). The model showed good fit (NFI
= 0.928; NNFI = 0.945; CFI = 0.954 – over the threshold of 0.90; SRMR
= 0.044; RMSEA = 0.086 – below the threshold of 0.10). Moreover, all
coefficients were found to be positive, high and significant. Also, the reli-
ability coefficients (Cronbach’s alpha = 0.952; RHO = 0.968, were high –
above the threshold of 0.70).
Figure 16 illustrates the standardized solution for the eco-innovation
construct, composed of the three dimensions of product, process and
organizational eco-innovation. The 15 items of these three dimensions
measure the entire eco-innovation construct. Table 57 offers results per-
taining to the standardized coefficients and their squares for all items of
the eco-innovation construct.
