Answer:
These new business structures such as corporations, trusts and holdings led to the growth of the industrialized economy simply because they could raise more capital than previous business structures.
Explanation:
Up until the Industrial Revoluton, most business structures were personally-owned, or family-owned. This meant that only one person, or a few people owned all the capital of the company, but they also bore all the risks: if the company failed, they had to pay off debtors with all their personal assets.
Needless to say, this made starting a business very risky, with the problem that the business structure probably did not allow to raise enough capital for the business to become truly profitable.
To solve this problem, new forms of business structures emerged. These structures allowed for more people to pool their money in the business endeavor, and also spread risk out among more partners or stockholders. Companies were now less risky to set up, and if they failed, the investors did not necessarily have to respond with all of their personal equity.
