Abstract: From the perspective of behavioral economics,according to the mathematical statistics model,this paper improves the index system on conscious selection for the Chinese sports lottery players,and compares results with related indicators of China Welfare Lottery and other lotteries abroad. We find that,the degree of conscious selection for the Chinese sports lottery players is pretty high,which mainly manifests as Gambler Fallacy;lottery rules will significantly affect the behavior of conscious selection.Paying attention to this behavior is of great significance to Chinese sports lottery institutions. Chinese sports lottery institutions should make reasonable rules to relieve the behavior of conscious selection,strategically increase the cap limit of single lot prize,continue to strictly control the high-frequency lotteries and promote the index system proposed in this paper to the international lottery field.
