Abstract: This paper aims to explore the impact of land consolidation on farmers’ cultivated land transfer based on the investigation of households in typical lobster and rice co-cropping area, Regression Discontinuity model was employed, and the affecting mechanism was tested. The results show that:（1）The implementation of land consolidation promotes the centralized operation of cultivated land. Land consolidation increases the probability of farmers transferring-in cultivated land by 16.0%~21.0%, but it does not have significant influence on farmers' transferring-out of cultivated land. Land consolidation increases the transferred-in cultivated land by 0.217 -0.314 hm², and the transferred-out area by 0.067 hm2-0.122 hm².（2）The implementation of land consolidation has effectively improved the quality conditions of cultivated land. Improvements of farmland flatness, accessibility to farmland roads, and irrigation and drainage infrastructure in the consolidation area have positively affected farmers' farmland transfer-out behavior, and the optimization of irrigation and drainage infrastructure has promoted the increase of farmland transfer area, while the improvement of farmland fragmentation has not effectively promoted the farmland transfer.（3）The improvement of cultivated land quality promotes the increase of cultivated land operation income and transfer price. The rise of cultivated land transfer price positively affected the probability and area of transfer-out farmland, and the rise of cultivated land operation income promotes the increase of the area of transfer-in farmland. Finally, suggestions are proposed based on this study. Firstly, we should intensify land consolidation in a targeted way to achieve the cultivated land value enhancement and increase the cultivated land operation income, and then improve the enthusiasm of farmers to transfer cultivated land. Secondly, we should accelerate the cultivation of new agricultural operators, encourage farmers to carry out appropriate scale management of cultivated land, and expand the demand for farmland transfer market. Thirdly, we should standardize the transfer behavior of cultivated land, and optimize the regulation of market price, to stabilize the supply of the transfer land.
