Industrial eco-economics is one of the critical branches of eco-economics. It is a subject of objective law of structural upgrading, functional optimization and highly efficient running of industrial eco-economic system, which is combined with industrial economic system and eco-system under the condition of intellectual economy and circular economy combinations. Meanwhile, it is a relatively weak subject in the research field of eco-economics in China for the time being. Taking the practice road of new type industrialization needs the guidance of industrial eco-economics. The modern industrial eco-economics in the 21st century must be adapted to the need of new type road of industrialization in China. The paper analyzes the status quo of research and the main contents of industrial eco-economics and tries to study some key theories of the branch subject.展开更多

Morphology and structure of the ovipositor in female Macrocentrus cingulum, a polyembryonic parasitoid, are observed in SEM studies. The ovipositor of M. cingulum consists of the valvulae 1, 2 and 3. The valvulae 1 and 2 of ovipositor house in the valvulae 3 at rest and the valvulae 1 and 2 part from the valvulae 3 at probing and ovipositing. The cross-section of valvulae 3 shows that the valvulae 3 is hollow which may reduce the weight of ovipositor and make the ovipositor more flexible. The distal end of stylus (valvulae l, 2) becomes extremely sharp and the piercing tip of valvulae 1 and 2 form the arrangement of tongue-and-groove. This arrangement may support valvulae 2 slide longitudinally along the valvulae 1. Numbers of pores are distributed on the cuticle of the valvulae l and 2. The piecing tip of valvulae 1 and 2 have more pores than proximal and intermediate region. The out side of valvulae 3 is completely covered with chactica sensilla and the distal end of valvulae 3 has more sensilla than proximal and intermediate region. The function and structure of ovipositor of M. cingulum was discussed and compared with other species.展开更多

We show that, in the process of evolution of labor share is characterized $6,000 per capita GDP (in PPP, 2000). We develop a model to explain this phenomenon that provides an in-depth explanation for Kuznets' inverted U hypothesis. Our findings indicate that the evolution of China's labor share is basically consistent with the model we have constructed. In addition, sectoral composition and the relative bargaining power of labor are also factors influencing labor share. These findings imply that labor share of primary distribution in China may enter an upward trajectory over the next two years. This process may be accelerated by the central government's policies for dealing with global financial crisis and by structural adjustment.展开更多
