A STUDY ON THE RELATIONSHIP BETWEEN TOBACCO ECONOMIC CHARACTERISTICS AND TOBACCO PLANTING INCOME BASED ON SHORT PANEL DATA OF 25 COUNTIES IN SHAANXI PROVINCE OF CHINA DURING 2015-2019

Based on the data for the economic traits of tobacco leaf in 25 counties of Shaanxi province in China from 2015 to 2019 obtained from Tobacco Science Research Institute of Shaanxi Province, a two-way fixed effect model was used to explore the influence of flue-cured tobacco economic characteristics on tobacco cultivation income. The empirical study showed that the large tobacco growers in Shaanxi Province lack the scientific and technological power matching with the scale of land management, the planting area and the unit yield; all these have significant negative effects on the tobacco cultivation income. The increase of tobacco planting income can be promoted by increasing the unit output value, total yield and purchase price of tobacco leaves. Based on the research findings, it can be concluded that the government in Shaanxi should encourage tobacco growers to choose the land management scale, suitable for them and is also in line with their own tobacco science and technology power. Besides, the cultivation technology training of tobacco growers needs to be strengthened, so as to improve the potential of tobacco growers.
