"Ideal type" can be translated as "理想型" in Chinese.

It originated from German sociologist Max Weber's concept of the "idealtypus", which refers to a theoretical construct used to describe and analyze social and economic phenomena. In Weber's work, the ideal type was used as a benchmark to compare and contrast actual social and economic conditions with the ideal.

For example:

"My ideal type of partner is someone who is kind, considerate, and has a good sense of humor."
(我的理想型伴侣是一个善良、体贴、幽默感很好的人。)

"The ideal type of society for me would be one in which everyone has equal opportunities and is treated fairly."
(对于我来说，理想型社会是一个人人都有平等的机会，并且受到公平对待的社会。)
