How to say "productive" in Mandarin and Cantonese? Google Translate says 生產的 效率 means efficient, but what is the word for productive in Cantonese and Mandarin?

CantoDict does not have an entry, and Google lists 生產的 which feels wrong.

For instance, let's say you want to translate this sentence into Cantonese and Mandarin: "Don't procrastinate then you can be productive."

Mandarin: 你別拖延先可以。。。？

Cantonese: ?
If you want to say that someone is productive, as in your example, you are basically saying that they are very efficient, therefore 效率 is the best term. 
 


  你效率很高 you are very productive (efficient)


In your example: 先别拖延，你就可以提高（你的）效率。 

For inanimate objects, 生产力 (productive strength) is the way to go, only difference being in Chinese you are using it as a noun.


  中国的生产力很高 China is a very productive country
