后危机时代虚拟经济与经济法的适应性问题分析

虚拟经济的健康发展是后危机时代主题之一,经济法律制度对此无疑起着支持与保障的重要作用。而当代经济法正面临着对虚拟经济形态的适应性困境,体现在它对市场的认知、对市场客体和市场运行的规制、对主体法律责任的规制等方面。在虚拟经济形态下,对经济法适应性不足的弥补应当从树立正确的自由观,提供有效的宏观调控和微观规制制度,构建市场主体经济法律责任算方面出发。     

The analytical solution of balanced growth of non-linear dynamic multi-sector economic model

In a one-sector neoclassical dynamic economic growth model, a reasonable ratio of investment to consumption exists, i.e., the “Golden Rule of Consumption”. This study is to extend one-sector neoclassical growth model to a multi-sector one. It is assumed that both the production function and the utility function are of Cobb–Douglas type, and the analytical expression of the balanced growth solution of the multi-sector model is provided, mainly including analytical expressions of the optimal distribution coefficient of fixed capital investment, the optimal distribution coefficient of labor hour, the proportion of production, the economic growth rate, the rate of change of the price index, and rental rates of different fixed capital.     

对我国外汇储备超适度规模的实证分析——基于改进的阿格沃尔模型

本文运用改进的阿格沃尔模型,选取1994-2010年数据对我国外汇储备适度规模进行了实证分析,结果表明:目前我国外汇储备规模已经明显过量。Johansen协整检验和Granger因果关系检验显示:进出口额、GDP、外商直接投资与外汇储备规模之间存在长期协整关系,对外汇储备规模能够产生长期的影响;但外债余额尤其是短期外债余额和广义货币供应量也能在短期内对外汇储备规模产生影响。本文认为,改善贸易结构并扩大内需,加大进口力度并支持对外投资,重视GDP的质量并促进经济理性增长,严格外企准入制度并转变外企引进结构,增强人民币汇率弹性等政策措施是抑制我国外汇储备过度增长的有效途径。

Distance measures between free trade and autarky for the world economy

We develop a methodology to determine numerically how globalized the world economy is. We present a global general equilibrium model capturing major OECD economies and a residual rest of world for which alternative metrics of distance between observed, free trade and autarky equilibria can be developed. We use data for 2000 and report a number of distance measures between the 2000 observed trade restricted equilibrium and both free trade and autarky equilibria noting the absence of prior literature on metrics of distance between equilibria. The measures are used to determine the degree to which the world economy is globalized.     

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.

农业保险供求与适度保费补贴率的确定

本文基于一定的假设条件,运用经济学供求理论,采用投保率水平度量农业保险的政策目标,建立了农业保险适度保费补贴率决定模型,揭示了适度保费补贴率变动的一般规律。基本结论是:在一定的农业保险政策目标条件下,适度保费补贴率决定于农业保险的公平精算费率与无补贴情况下农户的需求状况;适度保费补贴率随农业保险发展阶段的不同而不同,即随农业保险供求状况的变动而变动,其一般规律是从低到高,再从高到低的实现过程,因而应适时调整保费补贴政策。
