For a corporation, shareholders hold the ownership.
They own the property.
Normally speaking, it is not practical for so many shareholders manage the entity simultaneously.
They establish board of directors to control the entity.
Board of directors will hire senior managers, who normally don't have ownership in the entity.
Senior managers will have actual control over the daily operation, property handle and strategy execution.
Here we come to your final question.
所有制对高技术产业科技金融绩效的影响
First, I really don't understand your terminology of 科技金融 so much.
I have to try my best to stand on your shoes.
Do you mean the influence on its financial performance as an issuer?
if so, here is my opinion.
The ownership definitely has influence on its financial performance.
Generally speaking,
there are tremendous number of small high tech business in the world.
The business owners are normally research scientists.
They know nothing but their experiment. (statistically speaking)
If those guys have shares in the business.
They will have chance to enjoy the net profit after deducting all relevant expenses.
The incentive effect will be much better than being an employee.
Especially, when you have positive outcome.
Normally speaking,
those high tech practitioners won't have to contribute their capital,
they just contribute their patent or only their service.
But according to the initial contract, they will have guaranteed returns. (no matter entity is profitable or suffer a loss)
To offer high tech talents ownership is a routine conduct in modern world.
One of my friend just hired by Apple as a junior programmer.
He got $100, 000 shares stock option.
Do you think he will get lazy about it?
No, he and other guys with the options will work hard and try to boost the entity performance.
His share is definitely smaller than 5%.
He is not a 'owner' yet.
If you image he is a owner, what is he going to do?
He will do whatever he can to improve entity's performance.
In summary,
sound ownership will stimulate high tech business owners.
The final financial performance will normally be more promising in the future.
