CHANGE for a New Econornic Structure?

Opportunity in the financial crisis?For a long time,China's fast econom-ic growth is heavily dependent on growth of exports,particularly dependent on ex-ports of low value-added,low technologi-cal products.Although the policy-makers and scholars are aware of the importance and necessity of industrial structure im-provements since 1992,it is hard to have a real incentive to promote economic re-structuring under rapid economic growth.     

China''s Tough Road to Economic Recovery

Aseries of economic data recently showed that in the context of the global economic recession,China's economy may take the lead in recovery.     

长江经济带农业绿色生产效率及其时空分异特征研究

［目的］从静态分析和动态分析两个方面,阐释长江经济带农业绿色生产效率和农业绿色全要素生产率的时空分异特征以及生产率增长来源,以期为提高长江经济带农业绿色发展质量提供科学决策依据。［方法］文章基于资源环境约束的角度,利用MinDS模型和Global Malmquist Luenberger指数相结合的方法,测算长江经济带农业绿色生产效率和农业绿色全要素生产率,并将农业全要素生产率变化分解为纯技术效率变化（PEC）、纯技术变化（PTC）、规模效率变化（SEEC）和规模技术变化（SETC）4个部分。［结果］（1）长江经济带农业绿色生产效率水平较高,且呈不断增长趋势,下游地区的农业绿色生产效率高于中、上游,且中、上游与下游地区的差距不断拉大; （2）长江经济带农业绿色全要素生产率增长较快,以3年为1个周期,呈现波动式上升趋势,其增长主要源于纯技术进步和规模技术提高; （3）长江经济带下游农业绿色全要素生产率增长率最高,上游次之,中游最低,其中,下游农业绿色全要素生产率增长主要源于纯技术进步,中游是纯技术效率改进、纯技术进步和规模技术提高共同作用的结果,上游则源于纯技术效率改进、纯技术进步和规模效率提高。［结论］长江经济带上、中、下游三大区域的农业绿色发展水平和发展能力存在较大差异,需制定差异化政策,以调整农业增长模式,促进农业转型升级,实现高质量发展。

分享经济在西方的发展及其启示

分享经济自从20世纪70年代以来,在西方各国得到了长足的发展,但发展是不平衡的、各国有着各自不同的特点和优势。该文在回顾西方分享经济发展历史的基础上,归纳出了三个方面的启示:分享经济昭示了劳资关系的地位变化;分享经济的实现程度取决于"劳方"的谈判力和集体行动;分享经济的发展有赖于政府的积极引导。     

不同绿化基材配比对植物生长影响的试验研究

本文通过盆栽试验以不同因素不同水平进行正交设计,得到不同配比的基质,来研究基质的保水性和对高羊茅生长指标(发芽率、生长高度、生物量)的影响,通过极差和方差分析得出该试验的最优配方为A283C3D2,即因素A(有机无机复混肥)用量为0.48g,因素B(秸秆)用量为7.13g,因素C(液态地膜)用量为0.11g,因素D(保水荆)用量为0.57g,该试验为公路绿化恢复技术提供理论和技术依据.     

Strategic Responses to Competitive Pressure: The Case of Township and Village Enterprises in China

This study assesses the configuration between strategic orientation and industrial environment for Chinese township and village enterprises (TVEs), the organizational form which has played an increasingly important role in Chinese economic development and structural reform. We argue that the complexity, dynamism, and hostility of the industrial environment influence TVE managers' perception of competitive pressure, which in turn affects the firm's strategic orientations such as innovativeness, proactiveness, risk-taking, and analysis. Our analysis, based on a survey of TVE managers in Tinjin and Jiangsu, demonstrates that complexity and dynamism of industrial competition have a systematically positive impact on TVE's innovativeness, proactiveness, risk-taking, or analysis. Environmental hostility is not significantly associated with any strategic orientations adopted by Chinese TVEs. Implications of the findings are discussed.     

一个GDP动力学模型与货币金融政策

This article applies a dynamics approach in the research of monetary law of movement under the complex system of social economical operation, and characterizes the movement of money in a social institutional framework during GDP’s formation. Assuming that humans’ pursuit of the return of their money expenditure is a sensible course of nature, it defines the expression of money circulation velocity, and proceeds to deduce the basic differential equation of money circulation. By solving this equation, we can get the expression for a GDP dynamics model. After empirically testing the expression, this article draws a conclusion: GDP and the money in circulation (M₀) share the positive correlation when the monetary financial institution remains unchanged.
