摘　　要：分析供应链各方主体的行为逻辑和互动机制是理解商品市场过程的重要途径。结合海南省白沙黎族自治县等地调研资料,分析天然橡胶原料市场特征、主体行为逻辑以及博弈过程。研究发现:天然橡胶原料供应链存在一定的市场势力,在农户—中间商、中间商—初加工厂商交易阶段,购买方行使买方权利,给种植户带来双重边际效应;农户在原料市场交易中处于相对劣势的地位,是被动的价格接受者,在信息有限的行为决策参考中,农户在交易距离、干胶含量和挂牌价格之间进行权衡。以合作社为主体的产业联盟,与加工厂对接的直销渠道和收益共享契约机制,有助于提高小农户市场主体地位和市场参与能力,推动小农户与大市场有效对接。Analyzing the behavior logic and interaction mechanism of principal participants in the supply chain is an impor-tant aspect of understanding the commodity market.Combined with surveys in Baisha Li Autonomous County and other places,this paper tries to distinguish market characteristics,the decision-making process,and games in the filed exchanges of natural rubber.Results show that there is certainly market power in the supply chain of natural rubber raw materials.In the transaction stage of farmers-processors,processors-traders,the purchaser exercises the buyer’s rights which brings double marginal ef-fects to farmers;farmers are in a relatively disadvantaged position in raw material market transactions and are passive price receivers.In a behavioral decision with limited information,farmers trade off between trading distance,dry glue content,and price.By exploring the establishment of a cooperative-oriented rubber industry alliance,and the construction of direct mar-keting channels and revenue-sharing contract mechanisms with processing plants,we can improve the market position and market participation ability of small farmers and promote the effective docking between small farmers and large markets.
