• Per unit rice yield
• production potential
• rice production

In this study, the potential of using light, the historical yield evolution trend and the agricultural ecological zone (AEZ) methodology are exploited to calculate the "per unit yield" potential of Chinese rice. Results display how the maximum growth range of this value, calculated on countrywide farmlands, showed a decreasing tendency from 1961 to 2010. Achieved results are of significant importance to the Chinese rice production, because they show how the highest growth rate of Chinese rice yield production in different periods can be predicted using the rate of theoretical per unit yield.
