According to economic factors influencing farmers' income in the development process of tea industry, this paper, from the perspective of technology selection , uses farmer's technology selection hypothesis and multiple regression analysis. Based on micro- survey data from 284 tea growers in Xinyang city, Henan province, this paper analyzes the impact of labor- saving and labor- intensive technology selection on their income changes aiming at tea growers with different scales.The result shows that in the process of tea production, there are differences in rate of return on investment in labor- saving technology, the scale of tea gardens has a significant impact on tea growers' income. Large- scale tea plantations tend to use labor- saving technology,while small- scale tea plantations tend to use labor- intensive techniques. Therefore, this paper concludes that labor- saving technology and labor- intensive technology co- exist in the tea production process and tea production is still labor- intensive industry.
