Most ENG projects don't involve nearly anything that sensitive and deemed export controls exist a topic.
I don't know what ENG is but I'm not limiting this to any specific field. In all fields, foreigners are in general less trustworthy than Chinese people to China. If there are roles where this is little to no risk and the local Chinese talent is limited, foreigners can be used but in general, if nothing is sensitive and controlled, then it's not a critical area. We're talking more labor than education and China has the labor.
Brain circulation effects are small. Immigration effects to the receiving country are large.
I need to see studies for that claim. Immigration effects should be great but much more linear. Having people receive top education and come back to inject the local industry with ideas is a force multiplier.
What if I told you there are more countries than China & the United States and thus China accepting migrants from not the United States is possible?
Then I would reply that I never specifically said that migrants from only the US were unacceptable. I said migrants from countries that are hostile to China, such as Canada, Australia, India, etc... Then there are countries that are neutral and migrants from those countries are better but still not ideal because their loyalties can still be bought more easily than Chinese.
There's tons of micro-level data on migration.
That's not an answer. You claimed that the benefits are asymmetrical in favor of the US. How did you quantify it and what data are you using? And I know it's a gain for the US, but this means that you need to show that the gains for the US in labor are greater than the gains for China in training and information. And we know that China has used this method to leapfrog in technology.
Your seriously overestimating the value that "experience" brings vs. how much of engineering is just throwing the same set of techniques and slightly modifying parameters until shit works.
I don't believe you. You sound like you are dumbing down an incredibly intelligent field because you don't understand it. The whole tech world vies for top experts; countries fear their semiconductor/lithography experts going to China. By your reasoning, it's just a numbers game of people trying different stuff. Experts shouldn't matter (much).
China grows faster because of capital formation, not because of TFP growth. Immigration targets TFP, not capital formation.
Chinese tech gets major boosters from foreign tech being integrated and foreign-educated engineers adding what they know to start China on a higher point. China doesn't reinvent the wheel on everything. This leapfrogging is critical for fast rising.
Basically, China is accepting a labor deficit by sending students to the US but getting an education/information surplus, which it uses for its tech rush.
Tech loss is a post hoc cry of the United States.
No tech loss is an unsupported cry by you on this forum.
There's no empirical support for it and you see the immigration SMEs push against it
There are concrete examples of it happening with some Chinese being caught and many not as they return to China with US data and illegal tech exports. SMEs push for it because they want short term benefit of hard intelligent workers. The US government is trying to stop Chinese students from coming to the US for STEM because they see the trends and the long term benefits favor China and have favored China, causing US tech to lose dominance and several areas. The problem is the immediate short term unwinding that would be caused by their shortage.
Yeah, so China should accept migrants & students from other countries
Yeah, no. If there are cases where security is not an issue, but I don't really see any. Either it requires a lot of training and knowledge, so security should be an issue, or if it doesn't and it's just about labor, then local Chinese can do it. Maybe there are niche examples but from what I see, this is the major rule, not the exception.
China is a country built by the Chinese for the Chinese; it is not America v.2. China will never rely on immigrants.
