The aim of this research is to summarize the changes in wood distribution structure in Akita prefecture where there are forestry activities, as well as analyze the forestry policy and demand changes in recent years. For that purpose, we analyzed Japanese forestry statistics and reports, and in September 2017, we conducted interviews and field surveys in Akita prefecture. We conclude that the influence of wood producers on wood distribution structure has augmented due to two factors: the new distribution/processing system and the new production system that the Forestry Agency has implemented. We also show how the wood production in Akita prefecture has shifted from lumber to plywood after the supply of Natural Akita Cedar has exhausted. On the one hand, the woody biomass power generation has been further promoted after a new large woody biomass power plant in Akita prefecture started to operate, raising the demand for wood and changing the distribution structure. On the other hand, the higher demand for wood chips used for power generation started competing with the existing application, generating a disproportion between demand for wood and reforestation activities.

This research aims to examine the changing process in urban renewal policy in Shenzhen, a typical precursor of China's land system, and explore its relationship with urban villages (informal spaces), which have been an important spatial feature of China's rapid urbanization. The results show that there are three important phases of urban planning policy change. In the first phase, a period of nationalization and dualistic urban space formation led by the government. In the second phase, developers accelerated urban renewal in the form of 'demolition and redevelopment.' In the third phase, public housing was complemented by low-cost living space and the transformation of urban villages into a significant trend of 'comprehensive renovation (zonghezhengzhi)' with the retention of buildings and renovation. As demonstrated by recent policy changes, preserving the diversity of urban space is instructive for urban development.
