This reports a research work that measured the social capital of indigenous Kanakaney and Ibaloi vegetable growers and traders in seven highland communities of Benguet, in the Cordillera region, Philippines. The social capital index was calculated using an additive equation. The equation consists of measurable variables such as formal associations, trust, collective action and satisfaction and optimism. Six factors explaining social capital were extracted. Tests were used to check for relationships between social capital indicators and exogenous variables such as gender, educational attainment, religion, age and ethnicity. The effect of social capital on vegetable marketing is that possibly more efficient marketing arrangements are foregone in lieu of friendships and tribal ties, resulting in inefficiency and increased transaction costs for both parties. To prevent long term market inefficiency, the strength of informal networks can be employed to promote the formation of formal networks, inter-tribal transactions and a properly functioning institutional environment.

这份报告报告了一项研究工作，测量了菲律宾科迪勒拉地区Benguet七个高地社区的土著Kanakaney和Ibaloi菜农和商人的社会资本。社会资本指数的计算采用加性方程。这个等式由可测量的变量组成，如正式的联系、信任、集体行动、满意度和乐观主义。提取了解释社会资本的六个因素。研究人员使用测试来检查社会资本指标和外生变量(如性别、受教育程度、宗教、年龄和种族)之间的关系。社会资本对蔬菜市场营销的影响是，更有效的市场营销安排可能被放弃，取而代之的是友谊和部落关系，导致效率低下，增加了双方的交易成本。为了防止长期的市场无效，可以利用非正式网络的力量来促进正式网络的形成、部落间的交易和一个正常运行的制度环境。
