To determine whether logical and actual food demands are withinnatural regenerative ability, carrying capacity (excluding forestry production) is also calculated. Results show that actualdiet patterns were ecologically friendly in the period of 1982-2004 in China, mainly because of the rural moderate dietpatterns. But actual per capita footprint already overran its corresponding logic value of 0.976ha in urban areas in 2002.Productive areas for food production can satisfy the land requirement for actual diet patterns during the researchingperiod in China, nevertheless cannot satisfy that for balanced diet pattern or solve the problem of unbalanced ecologicalfootprint. The continual rising ecological footprint of food consumption in both rural and urban areas indicates that percapita footprint will keep on increasing in China and even may be more than the suggested logic value if no relevantcountermeasures are made to regulate diet patterns. Strictly speaking, China is facing food shortage, both in quality andin quantity.展开更多

It is possible to identify distinct occupational stains within the neighborhood, specifically in the cell one in this article, as a pioneer construction, due to housing dimension that corresponds to different housing typologies, residents and daily use areas, equipment. The objective is therefore, to understand how these three factors are reflected inside the cell, managing occupational stains which differ in space appropriation. How those different occupational stains that derive from the housing and urban morphology, may result in the occupation and experience of its inhabitants, not invalidating a cohesive structure of the neighborhood?展开更多

Why do some firms bypass patents? How is patenting developing within Chinese firms? This paper attempts to answer these questions using data of Chinese firms in the Yangtze River Delta region. Results indicate that, for product innovation, obtaining the lead time for market entry is of top priority in innovation protection, followed by confidentiality and patent protection. As for process innovation, confidentiality ranks first, followed by patent protection and obtaining the lead time. There is a significant and positive relationship between prior experience of patent licensing and possibility of future patent licensing. Firms with painful patent litigation experience tend to avoid it in the future. It is also found that there are great differences in patent behaviors between Chinese enterprises and their foreign counterparts.展开更多
