我国引进技术消化吸收与青少年成长教育类比分析及建议

消化吸收是我国技术引进后实现良性循环的重要环节,但目前一直存在效果不佳的问题。为了充分发挥技术引进的后发优势,通过应用相似系统理论,从我国青少年成长过程期间可能遇到的问题及预防措施来类比我国技术引进消化吸收工作中存在的不足,并给出相应的建议措施。     

Financial crisis and persistence: evidence from sticky expectations consumption growth model

We estimate the degree of stickiness in aggregate consumption growth for the U.S. considering the effects of the Great Recession. The behavior of stickiness estimate in the crisis is somewhat as the U-shaped pattern. Our findings imply that during the crisis consumers’ attentiveness to aggregate information has slightly increased, thereby reducing the persistence of aggregate consumption growth. However, the reduction in persistence is transitory. Since 1980, the U.S. faced five recessions and in most of them the degree of stickiness declined, albeit temporarily.     

中部地区金融发展与经济增长关系的实证研究

在“中部崛起”这一号召之下，中部金融业的发展如何能更有效地为其经济增长起到支撑作用显得尤为重要。本文运用回归分析和格兰杰因果检验法对我国中部地区六省1995-2004年金融发展与经济增长的关系进行实证研究，探求二者之间的因果关系，并在此基础上给出相应政策建议。这一研究对中部地区形成科学而有效的发展战略，实现经济振兴是有益的。     

Accounting for the wealth of Denmark: a case study of Smithian growth using the emergence of modern accounting in Danish dairying

Abstract

The idea of “Smithian growth” rests on a “natural” development out of agriculture through capital accumulation, and the division of labour. We confront these concepts with an “historical experiment” and the case of Danish agriculture in the nineteenth century. Specifically, we look at how accounting was used to promote specialization, ultimately in butter production, leading to the massive increases in productivity that Smith predicted. We also observe the emergence of Smithian “philosophers”. This ultimately led to the capital-intensive industrialization of Danish agriculture through butter factories, and general development. We argue that this establishes the historical relevance of Smith’s theories.     

THE JOINT ARRIVAL AND DEPARTURE PROCESS FOR THE M/M/l QUEUE

We consider the M/M/1-queue and derive an explicit expression for the joint distribution of the number of arrivals and the number of departures in [0, t), given the number of customers initially present. The derivation is almost purely combinatorial, it avoids the use of generating functions, and immediately yields a simple probabilistic interpretation of the result.     

人民币升值路径及其福利效果

人民币升值路径可以从时间路径和空间路径两个角度来进行研究。在多重的政策目标下，中国目前选择了渐进的升值方式，升值过程中名义汇率与物价水平共同调整。伴随有通货膨胀和资产价格泡沫的升值方式会从增量和存量两个方面改变社会的福利分配，这要求有相应的福利调整措施进行配套，以维护社会的公平和稳定。     

Persistence of Shocks to Output in Austria and Theories of Economic Growth

The paper analyzes the degree of output persistence in GDP in order toempirically discriminate between the Solow growth model, the perfect competition endogenous growth model and the imperfect competition endogenous growth model for the case of Austria. Wefind that a shock in the growth rate of output induces a permanent and larger effect on the level of GDP. This leads us to refute the Solow growth model and the perfect competition model of endogenous growth.We may not reject the imperfect competition growth model.     

Why England? Demographic factors, structural change and physical capital accumulation during the Industrial Revolution

Why did England industrialize first? And why was Europe ahead of the rest of the world? Unified growth theory in the tradition of Galor and Weil (2000, American Economic Review, 89, 806–828) and Galor and Moav (2002, Quartely Journal of Economics, 177(4), 1133–1191) captures the key features of the transition from stagnation to growth over time. Yet we know remarkably little about why industrialization occurred much earlier in some parts of the world than in others. To answer this question, we present a probabilistic two-sector model where the initial escape from Malthusian constraints depends on the demographic regime, capital deepening and the use of more differentiated capital equipment. Weather-induced shocks to agricultural productivity cause changes in prices and quantities, and affect wages. In a standard model with capital externalities, these fluctuations interact with the demographic regime and affect the speed of growth. Our model is calibrated to match the main characteristics of the English economy in 1700 and the observed transition until 1850. We capture one of the key features of the British Industrial Revolution emphasized by economic historians — slow growth of output and productivity. Fertility limitation is responsible for higher per capita incomes, and these in turn increase industrialization probabilities. The paper also explores the availability of nutrition for poorer segments of society. We examine the influence of redistributive institutions such as the Old Poor Law, and find they were not decisive in fostering industrialization. Simulations using parameter values for other countries show that Britain’s early escape was only partly due to chance. France could have moved out of agriculture and into manufacturing faster than Britain, but the probability was less than 25%. Contrary to recent claims in the literature, 18th century China had only a minimal chance to escape from Malthusian constraints.     

新型工业化与城乡二元工业化的协调发展

由于我国严重的“二元经济结构”和“双重演进”的制度变迁特征,形成了农村工业化和城市工业化同时并存的城乡二元工业化格局。城乡二元工业化格局在促进经济发展的同时,也形成了对经济发展的延迟效应。在新型工业化的实现过程中,既要实现以信息化带动工业化,又要推进城乡工业的协调发展,促进农业工业化的发展,加速完成经典工业化的任务。     

路径依赖的作用:家庭联产承包责任制的建立与演进

人地比例、耕作技术、土地产权制度之间的互动循环导致了中国历史时期土地产权制度演进中路径依赖的形成。中国目前人口与资源（土地）之间的紧张关系就是历史时期土地产权制度演进的结果，这一约束条件决定了中国土地产权制度只能是朝着更加周密细致地保证农民土地长期使用权与收益权的方向演进。从公社一级到三级所有、大队为基础，到三级所有、队为基础，再到家庭联产承包责任制的建立，直至承包期限由短期变为长期，由15年变为30年。这一步步的演进都是朝着保证农民土地长期使用权与收益权的方向回归，显现出制度变迁过程中路径依赖的作用。由于历史时期土地产权制度演进的影响，家庭联产承包责任制完善的方向应该是土地国家终级所有的前提下，强化农民现有土地长期使用权，并通过法律手段保证土地使用权的转让。
