Over the years, the implementation of land use planning has contributed significantly to socioeconomic development. To isolate the effect due to the land use planning from the total income increase we can apply method logic to solve by the program chain disintegration. If the input criterion for calculating gross income (or net income) is the gross product, the final result will be the product of the number of labors multiplied by the indicator of labor efficiency. The disintegration logic chain is as follows: (1) Breaking up the indicators of net income increase based on the function of labor efficiency and the number of labors, (2) Breaking up the increase due to the change of labor efficiency which depends quantity of gross product and material costs, (3) Breaking up gross product increase based volume of crop production, livestock, and other industries, (4) Breaking up net income increase by agricultural land due to the impact of factors including land area under irrigation, fertilizer, cultivate area, implementation of land use planning, weather factors and other factors. As a result, the increase of net product due to planning will be determined. With the data in 2000 and in 2010, the result of running the program chain disintegration shows that income growth in agricultural production due to the implementation of land use planning in the period from 2001 to 2010 of the Ham Thuan Bac district is 7.296,9 million VND, accounting for 7,08% of the total income generated by agriculture.
