PSM results: average income impact of NAC membership (in CNY).

Outcome	Matching algorithms	Treated	Controls	ATT	Std. err.		value
In 2018	Four-nearest	7741.788	7111.951	629.84	349.314	1.53	0.126
	Kernel	7741.788	7309.930	431.86	326.996	1.32	0.188
	Radius	7741.788	7114.520	627.27	349.175	1.53	0.125
	Nearest neighbor matching within caliper	7741.788	7326.127	415.66	326.351	1.24	0.217

Note. Significance level: , , and . ATT estimates of four-nearest neighbors, kernel (bandwidth = 0.06), radius (caliper = 0.06), and nearest neighbor matching within caliper (caliper = 0.06)-based matching are estimated using the “psmatch2” command in STATA.
