"因为工作量太大，公司HIRE了一个和我平级的新人。此人一来第一天，就对这里的环境大发议论，指指点点，很多都是不ACCURATE 或者不是重点。"
他这是急于在新地方确立自己的地位，不好但不少人这样做。新人到一新地方通常通过两种途径确立自己的地位：第一种是展现别人好他更好；第二种是别人都不好就他好。大多数人是第二种因为它比第一种容易。这么做反映了他的不安心理。
"会上经常问一些概念性错的问题，老板还说是GOOD POINT. 且经常在会上说VENDOR SUPPORT 不行，需要他来教他们。"
他是你老板挑出来的，你老板也渴望他的选择能得到别人的认可，表现出来就是这样偏袒维护之类无非是不想一下子就被认定选错了人。
"不仅如此，经常打断我和另外一个同事和别人的谈话，发表一同或者别人知道的，或者无厘头的话。"
还是前面说的一样道理他想确立自己的地位。经常打断别人的谈话 is a bad manner. 这时候你需要做的是观察分析一下自己，也是更好的了解一下自己的心理吧。For example, why发表一同或者别人知道的，或者无厘头的话 bothers you so much? Maybe it is because you are worried that your own position in the company is being challenged – this reflects your own insecurity.
"和他辩论，也常常没有结果，因为没有人懂你们两到底谁对谁错。"
Try to avoid arguing in front of people who do not understand. It only makes you look as bad as he does.
"他有很多东西不懂，就是通过这种办法来学东西，了解状况。一开始提出很多无厘头想法，然后和你争论，然后就从中学东西。
以上这是不是我个人的看法，组里另一个同事也和我相同的感受。
问题是老板听之任之，且有意无意的站在他这边。老板一是不懂，无法做判断，二我估计是为了平衡我，因为我最了解这里的情况。照理，我工作很好，且帮助公司很多，一个新来的，没有什么CREDIT，老板应该相信我多一点，这是人之常情，但是老板好像对我的态度视乎是和他一样，他一有想法，哪怕我觉得不make sense 的，老板都要拿出来讨论。讨论下来，老板也不下结论。"
Your boss only does something that bosses would normally do to their direct reports, i.e. (seemingly) impartial. It is perhaps your misconception that我工作很好，且帮助公司很多，一个新来的，没有什么CREDIT，老板应该相信我多一点. He is hired at the same position as yours, that means in your boss’mind he is as good and as credible as you are. And you need to accept it first. He is here to stay (at least for a while).
"请指教，策略上我应该如何办？不是想问谁对谁错，而是应该如何技巧的应付这类情况。"
My 2 cents:
First, you need to relax. It is he who needs to work hard to establish himself, not you. You don’t need to change your way of working if it has served you well in the past. Focus on yourself, improve yourself all the time, don’t let him distract you, and stop being obsessed by what he says or does.
Second, helping your boss is helping yourself, chat with your boss from time to time and find out what his worries are. Be reminded that your boss hired him. It may take time for your boss to realise and accept whether he’s made a good choice or not.
Be polite, be graceful and good mannered, give him opportunity to show what kind of person/worker he is. If he is a decent chap, he will become less aggressive once he feels he is accepted by his new colleagues. In the meantime, keep good terms with your boss, not to bad mouth him to your boss, spend some time and effort explaining technical details to your boss with a hint here and there that the ideas from the new hire may not be that great.
谢谢！
