Model Types	χ2/df	Change χ2	RMSEA	CFI	IFI
Five-factor model (expected model)	1.93	-	0.05	0.90	0.90
The best four-factor model (1: Perceived green HRM; 2: GPC; 3: HEP; 4: VGB + GC)	2.16	198.05 ***	0.06	0.87	0.88
The best three-factor model (1: Perceived green HRM; 2: GPC + HEP; 3: VGB + GC)	2.49	479.90 ***	0.07	0.84	0.84
The best two-factor model (1: Perceived green HRM + VGB + GC; 2: GPC + HEP)	2.82	758.59 ***	0.07	0.80	0.81
One-factor model (1: Perceived green HRM + VGB + GC+ GPC + HEP)	3.22	1101.91 ***	0.08	0.76	0.76

Notes: *** p < 0.01; GPC = Green psychological climate; HEP = Harmonious environmental passion; VGB = Voluntary workplace green behavior; GC = Green creativity.
