　This paper examines the role of social capital in a new environment conservation policy which aims at the conservation of the land, water and environment in rural regions launched in 2007. I focus on not only effects of bonding and bridging social capital themselves for it but an interaction effect of both types of social capital. I estimate these parameters while controlling other factors such as the geographic feature and production circumstances, treating rural communities as sample units. The empirical result certainly supports the presence of the interaction effect of them. This is a highly suggestive result; a plenty of bonding social capital can enhance the performance of bridging social capital for this new policy, and vice versa. Moreover, from the perspective of the accumulation, the negative correlation between bonding and bridging social capital is found. As a result, considering all of the above, the balance of the accumulation of both types of social capital is found to be the key for this new policy.
