Co-growth between big and small corporation

I saw the presentation about Co-growth between big and small corporation. They said small and mid size company have been deprived of their opportunity to enter some business parts which are managed by huge corporation. I think goverment need to arbitrate huge and small company in business. So they prohibit parent company from giving some subsidiary company a lot of business. Frankly I don't know well about small and huge company's relationship. but Ki Wook presentor said me in class, "Chong mong goo and his son invested 500 hundred millions 10 year ago, and they get 36000 hundred million as investment return. I think it is illogicality. If big com monopolize the one field in sales or society, samll com is died. It cause recession. I really agree to their presentaion and opinion. In my table yellow, 4 guys said Why is it problem in society? people don't know its importance. I think the best alternative is yielding each other. big company do not invade small's area. other hands, Small company give big com the opportunity to extention their area. and I think goverment should regulate the big and small company. Big corporation make the promise of cooperation. and goverment check the promise regularly. they give some incentive those fulfill the contract very well. When it comes to nation's economy, we definitely must solve the Win Win.
