Which of the following is a belief shared by the communist party and the socialist party? equal distribution of wealth a flat income tax rate for all individual-run private enterprise limited government interference in the economy

The correct answer is: "equal distribution of wealth"

Socialist and communist economic theories believe that the manner of creating an egalitarian and fair society, is to equally distribute all the income and wealth that a nation generates among its citizens. Therefore, they support an economic system which is centrally controlled by the goverment to ensure that this objective is met, instead of free interactions in the markets,  that they consider would lead to unequal and unfair outcomes .

explanation:

it was dumb and stupid town

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
