Mongolian nomadic culture and ecological culture: On the ecological reconstruction in the agro-pastoral mosaic zone in Northern China

After analyzing the grassland environmental characteristics and nomads vs. agrarian land use styles and their ecological and environmental influences in the arid and semiarid agro-pastoral mosaic zone in northern China, it was concluded that Mongolian nomadic culture is more close to the basic principles of the ecological culture in the modern sense. Mongolian nomadic culture has advantages over agrarian culture in ecology and environmental care, sustainable utilization of grasslands, and in sustainable human social economic development in the region. Generally speaking nomadic culture prevents desertification; whereas, agrarian culture facilitates desertification. Confliction between nomadic protection and agrarian destruction of grassland ecosystem is essentially focused on the problem of regional and even global ecological safety. Obviously, protection of ecological safety should be given priority because human social and economic existence, as well as development depend on and are decided by the vulnerable ecological safety in the arid and semiarid areas. Therefore expansion of cropping into the fragile ecosystem of arid lands was unfortunate. The long term sustainable management of these grassland ecosystems could benefit from reversal of policies that are exacerbating the problems of land degradation, and from the adoption of land use practices that have been successfully applied for centuries by Mongolian herders. Protection of grasslands and nomadic culture is far more important or even vital to the subsistence and sustainability of human and all other beings, compared to the protection of agrarian lifestyle and land cultivation. Protection of ecologic safety is protecting the premise and fundamental bases of economic and social development in the area. It is important to derive the rational elements of nomadic culture in construction of ecological culture, and in the ecological reconstruction in northern China. Based on analyzing and reasoning in line with the quintessence of nomadic culture summarized, some proposals on ecological reconstruction in the area are presented.

Order imbalance and stock returns: Evidence from China

We investigate the relation between daily order imbalance and return in the Chinese stock markets of Shenzhen and Shanghai. Prior studies have found that daily order imbalance is predictive of subsequent returns. On the two Chinese exchanges we find the autocorrelation in order imbalances is similar to that of the New York Stock Exchange as reported by Chordia and Subrahmanyam [Chordia, T., & Subrahmanyam, A. (2004). Order imbalance and individual stock returns: Theory and evidence. Journal of Financial Economics, 72, 485–518]. We also find a strong contemporaneous relation between daily order imbalances and returns. However, we do not find evidence that order imbalances predict subsequent returns. We attribute the difference in predicative power to differences in trading mechanisms on the two exchanges and to differences in the share turnover rates.
