5.2. Factor analysis of green logistics practices in truck fleets
In the survey,
the whole liability coefficient α of the development of green logistics practice of 104 Nanjing truck fleets was estimated to be 0.962.
Principal component analyses were used in the factor analysis.
Using orthogonal rotation with Kaiser standardized method,
with convergence after 8 iterations,
the KMO test coefficient = 0.884,
and Bartlett's sphericity test (df = 630, sig = 0.000).
Using factor analysis,
the 36 green logistics development drivers were extracted to 6 principal component factors.
They are environmental management of logistics factor,
low-carbon storage and packing factor,
low-carbon transportation factor,
fleet management factor,
the new alternative energy factor and logistics innovation factor.
Table 5 shows the results of factor analysis.
