The first systematic and fundamental research is did by Modigliani and Miler, they bring out with the famous MM theorem in 1958.Which says capital structure doesn't affect enterprise market value and average capital cost in a condition of perfect market. After that, several economists including Modigliani and Miler themselves put this theory forward with the MM theorem with the consideration of tax, the trade-off theory, the pecking order theory,market for corporate control, these analyses throw lights on the problem from different aspect.
