The Soft Engine for Economic Growth in a Long-Time:The Economic Development Power, Conversion and Conservation for economic Energy

Based on the theories of Development Power([18]-[20]) and Partial Distribution([21]-[24]), and combining with the actual economic development, this paper discusses the main ways how the Development Power (DP) is accumulated or released, establishes the analytic models of DP and the model of relation between DP and productivity; classifies economic development into the three states in energy¡ªthe state of normal energy, strong energy and super energy; gives the method of calculating the critical time of strong energy and super energy and the approach to describe the evolving process of these three states; puts forward the laws of conversion and conservation between mass and energy in economic developing. According to that DP is accumulated and released one after another, this paper points out, a sign that accumulation of DP is completed is the most of economic factors are in order, and the sign that release of DP is completed is the most of economic factors are in chaos, and also gives the ways to calculate the most possible time that the DP starts accumulating or releasing. Finally, the author make a comprehensive empirical analysis on all of results in this paper by means of the US GDP data from 1940 to 2003, the outcomes are satisfied. The conclusions in this paper make clear that the economic Development Power, namely economic development energy, is the engine for the economic growth.
