Agency 和Proxy从字面意思看，都有代理人的意思，二者有所区别。

Agent通常指的是商业和经济活动方面的代理

1、a person who manages business, financial, or contractual matters for an actor, performer, or writer即经纪人

2、A person or company that provides a particular service, typically one that involves organizing transactions between two other parties. 即中介，代理商

A travel agent旅行社

Shipping agents船运代理商

Letting agent出租中介

以上，agent做代理之意讲时，侧重于许可，一般指机构或个人

Proxy通常指代理权或受托人

1、the authority that you give to sb to do sth for you, when you cannot do it yourself即代理权；代表权。如：a proxy vote 由他人代投的票

2、a person who has been given the authority to represent sb else即代理人；受托人；代表

proxy at the shareholder’s general meeting 参与股东大会的代表

Your proxy will need to sign the form on your behalf. 你的代理人将须代表你在表格上签字。

以上，proxy做代理之意讲时，侧重于代表本人的参与。也是一种授权。
