That's key, but there have been lots of studies that deal with critical mass. When one looks at a regions ability to attract top talent, assembly plants, high calibre exhibits/pro sports/theatre, etc. there does seem to be a size where these things start to become feasible.
Just look at the Jets. If Winnipeg had 500,000 people in the metropolitan area, the NHL would not be coming to town no matter how popular the NHL is. Companies do look at size of market when deciding where to locate; IKEA being a well known example.
Would the Royal Winnipeg Ballet be sustainable in today's market if Winnipeg had 500,000 people? Would the CMHR have come to Winnipeg? There are a myriad things like this that do depend on city size.
Most of the studies I've read do point to 750,000-1,000,000 being the size when these critical building blocks start coming together for a city. Cities start thinking about LRT/subways at around 1,000,000+, they usually have hospitals large enough to attract top notch research, and airlines start contemplating regular frequent service (beyond the 1 or 2 incumbents).
When a city attracts something significant it acts as a magnet for others. More follows, which attracts yet more and more. It's a domino effect.
