If you look at the economy narrowly as purely making stuff then economics typically frames this within factors of production. These are land, labour, capital and possibly technology or entrepreneurship depending on how you define these terms. Land can contain the natural resources of the earth for simplicity's sake. These are the inputs as you describe.

But this is only really a part of the picture when considering what makes an economy where you get more into subjective value and coordination. The other comment is a rather good one.
