容易混淆的词
'Kekka' is a general result (can be good or bad), while 'Kouka' focuses on the effectiveness or intended influence of an action.
'Kouritsu' refers to efficiency (speed/resource usage), whereas 'Kouka' refers to effectiveness (the power to produce a result).
使用说明
Kouka is most commonly paired with the verbs 'aru' (to have) or 'deru' (to appear/show). It is used for positive or intended outcomes, except in the phrase 'gyaku-kouka' (backfire).
常见错误
Learners often forget that 'kouka' is a noun and try to use it as a verb without 'ga aru' or 'wo motarasu'. Do not say 'kouka suru' to mean 'to be effective'.
