DISCLAIMER: This question was asked as part of a crowdsourced consultancy. I am required to research and write an essay on the above title (although slightly modified to be more broad) and I'd like to gather your professional opinion on this topic.
First off, the tiananmen incident of 1989 seems to be an isolated incident at first, but upon reading up, it seems that at that time there was a lot of internal political instability and unstable economy because of the market reforms.
It seems that Deng Xiaoping removed Zhao Ziyang ( a reformist ) during the protests for supporting the protesters, but later went on to reform at an even greater pace. Why?
Did the incident spark any internal government hierarchy/system change?
This article by Time seems to say that a huge change happened (they split up politics and economy) but I haven't found any sources on it yet; also, why was such a change so successful?
I don't want to do your work for you.
Keep looking for sources on the politics and economy being split. I lived in China and this is absolutely true. You will be able to find sources.
My hint is, think about the nature and raison d'être of the Chinese Communist Party in a system that allows massive accumulation of wealth and a semi-free market.

Nothing is isolated, nothing 'just happens', everything happens because of the things that came before it. The issue of how Tienanmen impacted China must be looked at also in terms of what led up to the protest and what led the CCP to take the hard-line action it did.
(Deng Xiaoping) later went on to reform at an even greater pace. Why?
What do you mean by reform? Reform means so many things. What reforms did the protesters want? Zhao Ziyang? Deng Xiaoping? What reforms happened?
