The method of variance analysis was used to verify the effect of time limit and limit on the effect of time limit and limit under the condition of 500 pieces and 6 days under the same kind of discount level, 100 pieces and 1 day limit under the condition of limited time and 1 day, and the results are as follows: table 4 / 12. The method of variance analysis is used to verify the effect of time limit and limit under the condition of 500 pieces and 6 days under the same discount level, and 100 pieces and 1 day under the condition of limited time. When the discount intensity is small (20% discount), there is no significant difference between time-limited sales and limited sales on purchase intention, and when the discount intensity is large (60% discount), there is no significant difference between the two kinds of restrictions on purchase intention, when the restriction intensity increases, the influence effect of limit and limit on purchase intention is significantly different, and the effect of limited and limited sales on purchase intention is significantly different when the discount intensity is small (20% discount), and when the discount intensity is small (20% discount), there is no significant difference between limited and limited sales on purchase intention. Therefore, it is assumed that HLC is partially valid.
