中国报业集团化的隐忧和其解决方法的探讨

经过多年的摸索,中国报业终于明确了一条企业化、集团化的道路,很多学者也从理论上多方面地证明了它的可行性和重大意义,但是这条道路又伴随着新闻体制的基本方向和市场对利润的要求之间的矛盾、权力庇护下的经济不规模现象、新闻行业自身素质的匮乏等问题。解决这些问题,依赖政府在宏观调控上和新闻界在具体职能行使上的共同融合。     

Addressing shortcomings in the Household Responsibility System: Empirical analysis of the Two-Farmland System in Shandong Province

Despite apparent overwhelming benefits, implementation of the Household Responsibility System (HRS) in China contained a number of flaws. The Two-Farmland System (TFS), which originated in Pingdu City in Shandong Province, sought to address the twin problems of land fragmentation and economies of size. A stochastic frontier production function analysis that isolates the impacts of land allocation reforms suggests that the TFS increased efficiency by around 7%. This article highlights the need for empirical analysis to assess objectively the merits or otherwise of particular reforms.

我国粮食生产利益补偿机制研究

我国以粮食直补为主体的粮食生产利益补偿机制,对稳定粮食生产、保护粮食安全和增加农民收入有着较大的促进作用;但也存在补贴额度较小、粮食最低收购价偏低、补贴标准不统一、行政成本过高等问题,而且没有考虑粮食主产区农业基础设施建设等公共产品不足及其政府的积极性,同时,粮食补贴普惠制本身也有局限性。应加大粮食补贴力度、改变补贴方式、统一补贴发放标准、降低行政成本,适当提高粮食最低收购价,加大对粮食主产区的财政转移支付力度,增加粮食主产区农业基础设施建设补贴。     

Trajectories in human domination of ecosystems: Human appropriation of net primary production in the Philippines during the 20th century

The “human appropriation of net primary production” (HANPP) has been suggested as a comprehensive indicator to measure impacts of human land use on ecosystems. It accounts for (a) human-induced changes in biological productivity and (b) biomass harvest. This study presents an analysis of aboveground HANPP in the Philippines between 1910 and 2003, a period characterized by massive deforestation and increases in land use intensity and biomass extraction. Results show a steep increase of aboveground HANPP from just below 35% of potential productivity in 1910 to slightly above 60% in 1970 and constant values since then. Large-scale changes in land cover and agricultural practices were the main direct determinants of this trajectory in HANPP. Remarkably, HANPP grew at much slower pace than population did: While the amount of NPP appropriated by humans doubled throughout the period, population increased by a factor ten. Increasing efficiency in terms of biomass extraction per unit of area, relying on ever-increasing inputs, and changes in the nation's physical biomass trade balance were of major importance for this difference in growth rates. In the coming decades, the Philippines will have to face the challenge to meet increases in biomass demand without putting even higher strains on the ecosystems.     

物价波动、收入增长和地区差距对中国贫困线的影响

我国贫困线的增长机制是只与物价挂钩,不与收入挂钩。由于食品价格增长高于消费价格指数增长,这种调整机制导致贫困线绝对购买力下降;同时,随着收入的快速增长,贫困线相对购买力急剧下降。另外,贫困线与地区经济发展水平高度相关,造成地区间受助穷人的生活质量相差巨大。
