Change in producers' technology leads to a shift of the supply curve. Change in price leads to a movement within the supply curve.
Work Step by Step
The supply curve shifts only when there is a change in a relevant variable that is not named in either axis of the curve i.e a non-price determinant. In this scenario, it is the state of technology. The price is on the vertical axis of the curve, so a change in price is represented by a movement along the supply curve.
