转轨时期我国小农经济改造思想演变与争议

改造小农经济是转轨时期社会主义建设的最艰巨的任务之一。本从家庭经营、规模经营、农业产业化、农村剩余劳动力、农地制度创新等5个方面总结了理论界对小农经济改造的争议与研究，并认为改造小农经济应以邓小平“两个飞跃”理论作为理论基础。     

数字经济推动区域经济增长的实证研究——基于长江经济带2010-2019年数据

数字经济目前已经成为国民经济发展的重要推动力,研究数字经济对区域经济增长所起到的推动作用具有非常重要的现实指导意义。搭建数字经济发展测评体系和区域经济发展水平测量体系,通过对长江经济带2010-2019年相关指标数据的搜集,测算了长江经济带数字经济发展水平与整体经济发展水平,并对二者之间的耦合关系进行了验证,研究发现,长江经济带的整体数字经济发展水平相对均衡,数字经济对于区域经济增长有显著的推动作用,同时针对长江经济带数字经济助力经济增长给出了管理层面的建议。

Carbon Taxes and Joint Implementation. An Applied General Equilibrium Analysis for Germany and India

Germany has committed itself toreducing its carbon emissions by 25 percent in2005 as compared to 1990 emission levels. Toachieve this goal, the government has recentlylaunched an environmental tax reform whichentails a continuous increase in energy taxesin conjunction with a revenue-neutral cut innon-wage labor costs. This policy is supposedto yield a double dividend, reducing both, theproblem of global warming and high unemploymentrates. In addition to domestic actions,international treaties on climate protectionallow for the supplementary use of flexibleinstruments to exploit cheaper emissionreduction possibilities elsewhere. One concreteoption for Germany would be to enter jointimplementation (JI) with developing countriessuch as India where Germany pays emissionreduction abroad rather than meeting itsreduction target solely by domestic action. Inthis paper, we investigate whether anenvironmental tax reform cum JI providesemployment and overall efficiency gains ascompared to an environmental tax reformstand-alone. We address this question in theframework of a large-scale general equilibriummodel for Germany and India where Germany mayundertake JI with the Indian electricitysector. Our main finding is that JI offsetslargely the adverse effects of carbon emissionconstraints on the German economy. JIsignificantly lowers the level of carbon taxesand thus reduces the total costs of abatementas well as negative effects on labor demand. Inaddition, JI triggers direct investment demandfor energy efficient power plants produced inGermany. This provides positive employmenteffects and additional income for Germany. ForIndia, joint implementation equips itselectricity industry with scarce capital goodsleading to a more efficient power productionwith lower electricity prices for the economyand substantial welfare gains.     

汇率决定理论的新近发展:文献综述

传统汇率决定理论对于现实经济中汇率实际变动情况的解释能力十分低下.20世纪80年代以来,学术界不断寻求突破,以期为汇率如何决定这一基本命题提供更为合理的解释.在这一过程中,不断有新的文献出现,从不同的方面对传统的汇率理论进行补充、发展和替代.鉴于此,本文试图对汇率决定理论的新近发展进行梳理和介绍,借以为国内经济学界研究汇率决定问题提供一个理论参考.

How to control a chaotic economy?

An economic system which exhibits chaotic behaviour has been stabilized on various periodic orbits by use of the Ott-Grebogi-Yorke method. This procedure has been recently applied to controlling chaotic phenomena in physical, chemical and biological systems. We adopt this method successfully for Feichtinger's generic model of two competing firms with asymmetrical investment strategies. We show that the application of this control method to the particular economic process considered brings a substantial advantage: one can easily switch from a chaotic trajectory to a regular periodic orbit and simultaneously improve the system's economic properties. Numerical simulations are presented in order to illustrate the effectiveness of the whole procedure.The work was supported by the Alexander von Humboldt-Stiftung and by the Polish National Council (KBN) Grant No 2 P302 038 04.

循环经济认知误区的实证分析

随着传统经济增长模式危机的出现，世界各国纷纷提出并开始建立循环经济。循环经济作为一种崭新的社会经济发展模式，人们对其认识还存在种种误区，其中认为循环经济是一种最终实现“全新的封闭式的零排放的资源利用方式”、“可解决一切环境问题”的观点最为典型。那么，是否真的存在完美的全社会物质循环呢？实现这种循环的代价是什么？本文以物质循环为基本假设条件，应用扩张环境分析用投入产出模型对社会实现全循环的可能性进行了理论探讨．并以日本为例应用该模型对日本物质循环现状和在现有条件下实现全循环的可能性及其成本进行了实证分析，论证了在现有条件下实现全社会完美的物质循环的难点。
