referring to the idea of "principles of economic life". Mankiw's list of 10 principles (below) is a good example of this notion. These are principles of how the economy works (or should work), hence, they refer to the economy or economic actors.
Principles of Economics:
referring to the basic methods &concepts economists use when doing economics, hence to economic analysis. In this view the term "economics" refers to the discipline, not to the economy.

How People Make Decisions
To get one thing, you have to give up something else. Making decisions requires trading off one goal against another.
Decision-makers have to consider both the obvious and implicit costs of their actions.
A rational decision-maker takes action if and only if the marginal benefit of the action exceeds the marginal cost.
Behavior changes when costs or benefits change.
How the Economy Works as A Whole
Trade allows each person to specialize in the activities he or she does best. By trading with others, people can buy a greater variety of goods or services.
When a market fails to allocate resources efficiently, the government can change the outcome through public policy. Examples are regulations against monopolies and pollution.
How People Interact
Countries whose workers produce a large quantity of goods and services per unit of time enjoy a high standard of living. Similarly, as a nation's productivity grows, so does its average income.
Reducing inflation often causes a temporary rise in unemployment. This tradeoff is crucial for understanding the short-run effects of changes in taxes, government spending and monetary policy.
