What is the meaning of 有针对性地
然后（企业）可以有针对性 地 给员工补充“能量”。

As you may have known, in Chinese adding double quotation mark to word indicates it(the word) means something beyond its literal meaning.

能量's literal meaning is energy.
In your case, 能量 means the skills or abilities that employees need.

然后（企业）可以有针对性 地 给员工补充“能量”。

Literal Meaning: Afterwards company can refill(补充) the energy(能量) for employees accordingly(有针对性地).

Employees are not machines so they don't actually need to refill energy to perform better. They need more skills or abilities. The way to give someone skills or abilities is to train them.

So the actual meaning of the sentence is： Afterwards/Then company can give training (补充“能量”) to its employees accordingly.

I hope this answer helps.
