There are many other divisions and subdivisions of businesses. The authoritative list of business types for North America is generally considered to be the North American Industry Classification System, or NAICS. The equivalent European Union list is the Statistical Classification of Economic Activities in the European Community (NACE).
 ManagementThe efficient and effective operation of a business, and study of this subject, is called management. The main branches of management are financial management, marketing management, human resource management, strategic management, production management, operation management, service management and information technology management.
 Reforming State EnterprisesIn recent decades, assets and enterprises that were run by various states have been modeled after business enterprises. In 2003, the People's Republic of China reformed 80% of its state-owned enterprises and modeled them on a company-type management system. Many state institutions and enterprises in China and Russia have been transformed into joint-stock companies, with part of their shares being listed on public stock markets.

Most legal jurisdictions specify the forms of ownership that a business can take, creating a body of commercial law for each type.
The major factors affecting how a business is organized are usually:
- The size and scope of the business firm and its structure, management, and ownership, broadly analyzed in the theory of the firm. Generally a smaller business is more flexible, while larger businesses, or those with wider ownership or more formal structures, will usually tend to be organized as corporations or (less often) partnerships. In addition, a business that wishes to raise money on a stock market or to be owned by a wide range of people will often be required to adopt a specific legal form to do so.
- The sector and country. Private profit-making businesses are different from government-owned bodies. In some countries, certain businesses are legally obliged to be organized in certain ways.
- Limited liability. Corporations, limited liability partnerships, and other specific types of business organization protect their owners or shareholders from business failure by doing business under a separate legal entity with certain legal protections. In contrast, unincorporated businesses or persons working on their own are usually not so protected.
- Tax advantages. Different structures are treated differently in tax law, and may have advantages for this reason.
- Disclosure and compliance requirements. Different business structures may be required to make less or more information public (or report it to relevant authorities), and may be bound to comply with different rules and regulations.
Where two or more individuals own a business together but have failed to organize a more specialized form of vehicle, they will be treated as a general partnership. The terms of a partnership are partly governed by a partnership agreement if one is created, and partly by the law of the jurisdiction where the partnership is located. No paperwork or filing is necessary to create a partnership, and without an agreement, the relationships and legal rights of the partners will be entirely governed by the law of the jurisdiction where the partnership is located.
A single person who owns and runs a business is commonly known as a sole proprietor, whether that person owns it directly or through a formally organized entity.
A few relevant factors to consider in deciding how to operate a business include:
- General partners in a partnership (other than a limited liability partnership), plus anyone who personally owns and operates a business without creating a separate legal entity, are personally liable for the debts and obligations of the business.
- Generally, corporations are required to pay tax just like "real" people. In some tax systems, this can give rise to so-called double taxation, because first the corporation pays tax on the profit, and then when the corporation distributes its profits to its owners, individuals have to include dividends in their income when they complete their personal tax returns, at which point a second layer of income tax is imposed.
- In most countries, there are laws which treat small corporations differently than large ones. They may be exempt from certain legal filing requirements or labor laws, have simplified procedures in specialized areas, and have simplified, advantageous, or slightly different tax treatment.
- To "go public" (sometimes called IPO) -- which basically means to allow a part of the business to be owned by a wider range of investors or the public in general—you must organize a separate entity, which is usually required to comply with a tighter set of laws and procedures. Most public entities are corporations that have sold shares, but increasingly there are also public LLCs that sell units (sometimes also called shares), and other more exotic entities as well (for example, REITs in the USA, Unit Trusts in the UK). However, you cannot take a general partnership "public."
 Commercial law
As for other laws that regulate or impact businesses, in many countries it is all but impossible to chronicle them all in a single reference source. There are laws governing treatment of labor and generally relations with employees, safety and protection issues (Health and Safety), anti-discrimination laws (age, gender, disabilities, race, and in some jurisdictions, sexual orientation), minimum wage laws, union laws, workers compensation laws, and annual vacation or working hours time.
In some specialized businesses, there may also be licenses required, either due to special laws that govern entry into certain trades, occupations or professions, which may require special education, or by local governments. Professions that require special licenses range from law and medicine to flying airplanes to selling liquor to radio broadcasting to selling investment securities to selling used cars to roofing. Local jurisdictions may also require special licenses and taxes just to operate a business without regard to the type of business involved.
Some businesses are subject to ongoing special regulation. These industries include, for example, public utilities, investment securities, banking, insurance, broadcasting, aviation, and health care providers. Environmental regulations are also very complex and can impact many kinds of businesses in unexpected ways.
 Capitalcapital'), more laws come into play. A highly complex set of laws and regulations govern the offer and sale of investment securities (the means of raising money) in most Western countries. These regulations can require disclosure of a lot of specific financial and other information about the business and give buyers certain remedies. Because "securities" is a very broad term, most investment transactions will be potentially subject to these laws, unless a special exemption is available.
Capital may be raised through private means, by public offer (IPO) on a stock exchange, or in many other ways. Major stock exchanges include the Shanghai Stock Exchange, Singapore Exchange, Hong Kong Stock Exchange, New York Stock Exchange and Nasdaq (USA), the London Stock Exchange (UK), the Tokyo Stock Exchange (Japan), and so on. Most countries with capital markets have at least one.
Businesses that have gone "public" are subject to extremely detailed and complicated regulation about their internal governance (such as how executive officers' compensation is determined) and when and how information is disclosed to the public and their shareholders. In the United States, these regulations are primarily implemented and enforced by the United States Securities and Exchange Commission (SEC). Other Western nations have comparable regulatory bodies. The regulations are implemented and enforced by the China Securities Regulation Commission (CSRC), in China. In Singapore, the regulation authority is Monetary Authority of Singapore (MAS), and in Hong Kong, it is Securities and Futures Commission (SFC).
As noted at the beginning, it is impossible to enumerate all of the types of laws and regulations that impact on business today. In fact, these laws have become so numerous and complex, that no business lawyer can learn them all, forcing increasing specialization among corporate attorneys. It is not unheard of for teams of 5 to 10 attorneys to be required to handle certain kinds of corporate transactions, due to the sprawling nature of modern regulation. Commercial law spans general corporate law, employment and labor law, health-care law, securities law, M&A law (who specialize in acquisitions), tax law, ERISA law (ERISA in the United States governs employee benefit plans), food and drug regulatory law, intellectual property law (specializing in copyrights, patents, trademarks and such), telecommunications law, and more.
In Thailand, for example, it is necessary to register a particular amount of capital for each employee, and pay a fee to the government for the amount of capital registered. There is no legal requirement to prove that this capital actually exists, the only requirement is to pay the fee. Overall, processes like this are detrimental to the development and GDP of a country, but often exist in "feudal" developing countries.
 Intellectual propertyBusinesses often have important "intellectual property" that needs protection from competitors for the company to stay profitable. This could require patents or copyrights or preservation of trade secrets. Most businesses have names, logos and similar branding techniques that could benefit from trademarking. Patents and copyrights in the United States are largely governed by federal law, while trade secrets and trademarking are mostly a matter of state law. Because of the nature of intellectual property, a business needs protection in every jurisdiction in which they are concerned about competitors. Many countries are signatories to international treaties concerning intellectual property, and thus companies registered in these countries are subject to national laws bound by these treaties.
