农村经济转型期不同类型农户共生能力研究:以重庆市合川区大柱村为例

On Symbiosis Capability of Different Rural Household Types in Rural Economic Transition Period:A Case Study of Dazhu Village,Hechuan District,Chongqing

农户作为农村经济转型及经济建设的微观行为主体,渐由"个体"转向"共同体",发展模式逐渐由"竞争"趋向"协作",准确判别农户间共生能力对合理引导农户生产、促进和谐乡村建设具有重要意义.研究引入共生理论,以农户分化为基础划分农户共生单元,以农户年收益值作为主质参量,通过共生度及共生系数模型对农户共生单元间共生能力进行分析,结果表明:1农户共生单元间均只存在正向共生关系,不存在寄生或偏利共生关系,农户共生单元之间新能量流的非对称性降低,逐渐向对称性互惠共生关系进化;2不同类型农户共生单元间影响程度差异明显,兼业发展型农户与非农发展型农户间的共生能力最强,其达到对称性互惠共生阶段所需时间也最短.

T he farmers ,as the microscopic behavior subject of the rural economy transformation and eco-nomic construction ,have gradually turned from “individual” to “community” ,with its development mode also turned from “competition” to “cooperation” .Accurately distinguishing farmers symbiotic capability can guide rural household＇s production reasonably and promote to build a harmonious village .In this study the theory of symbiosis and divides farmer symbiotic unit has been introduced on the basis of the farmers differentiation ,taking farmer＇s annul income as the intrinsic parameter and dividing time interval ,and then analyzing farmers symbiotic capability through the model of symbiotic degree and symbiotic coefficient . Results show that farmer symbiotic units just exist positive symbiotic relationship and have no parasitic and dominance symbiosis during 2002~2011 ,but their asymmetry of new energy flow is gradually reducing and will be towards symmetric mutual symbiosis .Farmer symbiotic units have different interactions which expressed for the agricultural development is highest and the non-agricultural development is lowest .In addition ,the symbiotic capability between part-time development type＇s farmers and non-agricultural de-velopment type＇s farmers is greatest and the time is shortest to arrive at the step of symmetric mutual symbiosis .
