What channels do economic information and material price changes come from?

1, I know a price network that can check the prices of some things.

2. As an ordinary person, economic information can be learned through economic and financial magazines and some professional financial news.

3, directly through the network search, judge for yourself, there is too much information.

I suggest you browse more economic and financial websites and collect some for your next search. Of course, these financial websites had better be professional. For example, NPC Economic Forum, Statistical Yearbook, Wall Street Journal, etc. Of course, if you are interested, you can go directly to official website and the National Bureau of Statistics to download their public information. There is a lot of data.
