EVALUTING FARMING EFFICIENCY TO HIGH QUALITY RICE IN AN GIANG
Abstract
The research is conducted in order to evaluate the efficiency in farming of high quality rice in An Giang province, associated with the strategic orientation of rice export market in Viet Nam. Data envelopment analysis (DEA) was used to estimate efficient farming with size variable return to scale and efficiency farming without size in variable returns to scale. On variable return to scale, the average of technical efficiency was 87,05%, the average of allocating efficiency was 78,37%, the average of cost efficiency was 67,99%. On invariable returns to scale, the average of technical efficiency was 80,91%, the average of allocating efficiency was 63,80%, the average of cost efficiency was 58,32%. Tobit model appeared dependent variable to efficient farming returns to scale and independent variable offered to define factors that affected farming efficiency. As a result, the research identified 04 influential factors to farming efficiency including profession, experiences, farming agreement, and quantity of seed.
