Note. The actual values of variables involved in this study are shown in Henan Statistical Yearbook. Among them, the actual value of Grain output per hectare = (Grain output  10,000)/Sown area of grain, ESTIGP = Internal expenditures on R&D  Gross output value of agriculture/Gross domestic product  Sown area of grain/Total sown area of farm crops, PSTIGP = R&D personnel  Gross output value of agriculture/Gross domestic product  Sown area of grain/Total sown area of farm crops.
