科技服务业产出测算：指标确立、数据收集与未来预测

科技服务业产出测算是对科技服务业产出数据的统计与分析，加强科技服务业产出数据的规范统计和应用分析可为我国政府调整产业政策提供重要数据支撑。以科技服务业产出测算为研究对象，结合学者观点、国家标准及各级政府相关产业政策，提出将分支产业作为初始指标的横向统计思路，构建科技服务业产出测算指标体系。在数据收集方面，强调要做好“收”与“填”两个基本工作；在指标确立和数据收集基础上，进一步提出未来预测的两种方法，以此作为科技服务业产出数据预测的初步探索；提出应从统一数据统计标准、完善数据调查与公开制度、加强数据资源开发3个方面建立健全我国科技服务业产出数据测量与管理体制机制。     

循环经济的投入产出分析

本文运用投入产出理论对循环经济进行了量化分析，首先，在模型中将循环经济部门从生产部门和消除污染部门中分离开来，在投入不变的条件下，运用循环经济下的各种经济指标来研究新的投入产出关系。其次，通过比较研究的方法，来分析循环经济对整个国民经济的影响程度及对其效果进行评价。最后本文还探讨了在不引入循环生产部门的情况时循环经济的投入产出关系。     

中国的潜在产出、产出缺口及产量--通货膨胀交替关系--基于"Kalman滤波"方法的研究

本文介绍并运用“Kalman滤波”方法估计1979-2004年间我国的潜在经济增长率和产出缺口，然后根据这些结果检验了我国经济增长与通货膨胀率之间的交替关系、社会的通货膨胀预期对经济的影响、决定产出缺口大小的影响因素等，最后利用研究结果对我国2005年的经济发展进行了预测。     

An Eclectic Approach to Estimating U.S. Potential GDP

Rennison (Comparing alternative output gap estimations: a Monte Carlo approach, 2003) has provided simulation-based evidence showing that the joint use of extended multivariate filters and structural vector autoregression models is optimal for estimating potential output. We use this approach to estimate the two components of potential GDP: the full-employment labour input and trend labour productivity. This decomposition is useful for identifying sources of fluctuations in potential output. It reveals, for example, that the vigorous growth rate of U.S. potential GDP recorded during the second half of the 1990s is attributable to a fall in the structural rate of unemployment and a marked upswing in trend productivity growth.     

中美公众对收入差距的反应差异探讨

中美的基尼系数如实地反映了两国的收入差距。中美两国民众对收入差距反应有差异的原因是因为两国的收入分配形状、社会保障水平、经济发展水平、非法收入的社会影响不同。由此可得出这样一个结论：要缩小我国收入差距，就必须在农村实行规模经济，完善社会保障，加大打击非法收入的力度。     

产出吸引、制度演进与增量改革的产权边界——基于中国制度演进路径的动态考察

制度演进理论将制度变迁行为归结为制度主体对环境的学习和适应过程,在完全信息和缺乏外在约束条件下,制度将会按照某种方式向最优的均衡路径逼近。但是,信息的不完全性、经济实体的制度兼容性以及转轨经济面临的产权、效率约束都会改变制度演进的路径和结果。根据Barro(1991)和Skott(1999)的分析框架,通过构建制度的动态演进方程,文章对在一定约束条件下的制度演进长期均衡路径进行了考察,勾勒出一幅全新的制度演进图景。同时,运用相关的宏观经济数据,文章考察了模型对中国经济制度演进路径的解释能力。     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

Analysis and Forecast of the State of Environmental Protection in Russia

The main purpose of the present study is to analyse the emission dynamics of atmospheric and water pollutants in Russia and cost of their removal in the 1980s and early 1990s, and to forecast them by means of a Dynamic Input–Output Model according to different scenarios of future economic development till 1998. Main results of the work are:– methodological principles have been elaborated for singling out the environmental protection sector within the national economy;– a method has been offered for including the ecological block into a Dynamic Input–Output Model of the Russian economy;– a method of data preparation has been elaborated for the ecological block of the above-named model, the data base which characterizes the ecological situation in Russia has been formed and analysed;– calculations for 1994–1998 have been executed for forecasting the economic and ecological development of Russia using the above-mentioned model and the results obtained have been analysed. The results showed that if the existing tendencies towards low environmental protection capital costs remain the same, then the negative environmental impact will increase. In order to implement ecological programs and international agreements, to increase the proportion of removed pollutants, it is necessary to increase substantially expenditures on purifying water and air resources. The proportion of environmental protection investments in the total amount of the national economy capital costs should increase by up to 12–40% according to different scenarios of the economic development and different purposes of the environmental protection policy.     

中国的经济发展战略与地区收入差距

本文认为 ,当前中国大陆各省区市之间发展水平差距的主要原因在于 ,重工业优先发展的赶超战略下形成的生产要素存量配置结构 ,与许多省区市的要素禀赋结构决定的比较优势相违背 ,从而导致大量的赶超企业缺乏自生能力。基于各省区市的数据进行的实证研究与我们的假说相容。     

对收入差距问题的思考

目前，我国的收入差距尚在可控制范围之内，我们应根据收入差距的不同成因采取不同措施对其进行合理调节，但这种调节并不必然会带来收入差距缩小的结果，税收在当前也不是一种有效的调节手段。
