The most important reforms implemented by Louis XIV were reforms that were meant to consolidate power for himself. For example, Louis reorganized the central government to take power away from the high nobility. He did not want people with really high titles to be powerful so that they could not challenge him. Therefore, he reformed government by removing them from power and putting lesser nobles (whom he could more easily control) in their places. Similarly, Louis XIV also increased the number of intendants and their powers. He wanted them to help him impose his control over the peripheral areas of France.
These types of reforms were meant to make the government of France run more efficiently and to have the power be centralized in his own hands.
