The Bahrain Grand Prix winner found that lessons he had put to good use to win in Malaysia had been taken on board by team-mate Rosberg in the next race, thanks to the open data policy that exists within Mercedes.
GP analysis: Hamilton wins Rosberg's race
Following a weekend where Rosberg ended up with the quicker car, Hamilton intends to study where he has to improve in the hope he can triumph again in China.
"It could have been a lot different right now - the pain I would have been feeling in my heart having lost after leading the race, or being quick early on in the weekend," said Hamilton.
"But I'm relaxed, I'm happy. But I also know there is a lot of work to do.
"I know that I lacked a little bit of pace, I didn't have the pace that I had last week [in Malaysia].
"So I'm going to study hard these next two weeks and I'm going to be giving it a lot of thought."
He said Rosberg had gone into a lot of depth to analyse his Malaysia performance.
"Someone in the team did a huge study on my pace last week and, as I arrived here this weekend, there was this big document with all the reasons why I was quick. And he used that to his advantage," said Hamilton.
"So I'll do the same and hope that it works for me."
