Empirical researches indicate that (1) listed companies with good news in last year disclosure first quarter financial reports earlier than listed companies with bad news in last year under the condition of listed companies with good news in first quarter; (2) listed companies with good news in first quarter disclosure annual financial reports earlier than listed companies with bad news in first quarter under the condition of listed companies with good news in last year; and (3) listed companies with good news in last year disclosure first quarter financial reports earlier than listed companies with bad news in last year under the condition of listed companies with bad news in first quarter because managers have some combinatorial motivation and information manipulation in information disclosure due to last annual financial reports and first quarter financial reports are both required to be published by the end of April 30 of every year. The disclosure timing of annual financial reports and first quarter financial reports mainly rests with combination and balance of positive effect along with “good news” and negative effect along with “bad news” published in last annual financial reports and i
