辽宁省内向FDI与对外贸易关系研究

随着经济全球化的稳健发展,FDI和国际贸易日渐成为两种最重要的国际经济活动,贸易投资一体化已然成为贸易和投资的主流。采用1990—2013年数据,通过图表等形式分别从总量、比重等方面对辽宁省FDI与国际贸易的现状进行分析,总结出二者发展的特点。同时分别从贸易进出口和贸易方式两大方面对二者的关系进行实证研究,通过单位根检验、协整检验以及格兰杰因果检验,指出FDI与贸易进出口双向存在因果关系,与贸易方式存在正向相关关系,并提出政策建议。     

Energy Substitution,Separability, and Technical Progress in the Australian Iron and Steel Industry

The effects of the “energy crisis” on the Australian iron and Steel industry are analyzed by using a flexible functional form, the transcendental logarithmic (translog) function, which represents a second-order approximation of any twice differentiable function. The robustness of the translog is analyzed with special attention paid to factor aggregation and separability conditions as they relate to the specification of the functions. The estimation results suggest that capital and energy are substitutes, that aggregation of administrative workers and production labor is inappropriate, and that materials are weakly separable, thereby allowing the estimation of a capital, labor, and energy model. The data set developed covers the financial years from 1946–47 to 1978–79. This 33-year time series allows the use of different temporal subsets. Technical progress is shown to be capital and energy using and labor and material saving. An energy submodel is specified using solid fuels, oil, electricity, and gas; and the interfuel substitutions are estimated.

混沌时间序列分析法在生产总值预测中的应用分析

国内生产总值是国家经济建设中一个重要的参数,是衡量国家经济实力和经济发展规模的重要指标,利用混沌动力学原理,采用相空间重构技术的混沌时间序列分析法,对改革开放以来(1978-2004年)我国国内生产总值(GDP)时间序列进行了分析,计算了时间序列的嵌入维数、延迟时间等关键参数,建立了局域预测模型。并且把预测结果和用灰色系统预测结果进行了比较。结果表明,用混沌时间序列分析法预测国内生产总值具有较好的精度。     

论西部开发战略对固定资产投入和产值的影响

通过数据计算和图表分析，从绝对数量和增长速度两个方面说明了西部开发战略对固定资产投入和西部产值的影响程度，建议国家在抑制固定资产投资增长过快时，应对西部给予区别对待；在实施西部开发战略时，除国家支持外，还应重视东部对西部的支持。

Measurement Problems of Inflation Disaggregation

Why do the three quarterly GNP inflation measures differ so much when they are constructed from the same underlying price data? Algebraically and in tables using data of the second quarter of 1984, it is shown that these differences occur because of quarterly shifts in the composition of the nation's product. Disaggregation of the inflation contributions of the GNP components also makes it clear why, for quarterly analyses, the GNP chain price index is superior to both the implicit GNP deflator and the fixed-weight GNP price index. In particular, the implicit GNP deflator can give severely distorted inflation signals.     

天然气操作成本影响因素分析方法研究

以HTB气田为例,首先采用帕累托原理和灰关联分析,找出气田操作成本中的主要影响因素和各分项费用与操作成本之间的关联度,再采用指数分析法精确地描述其变动的影响因素,从而全面、准确分析天然气操作成本变动情况,为天然气成本控制和提高气田的经济效益提供科学依据。     

A note on james type robust estimators

M-estimation of a single parameter of the life time distribution is considered based on independent and identically distributed survival data which may be randomly censored. The most robust and the optimal robust M-estimators of the location parameters of the survival time distribution are derived within a class considered in James (1986) as well as for the general unrestricted class. The properties of the estimators corresponding to the above two classes are discussed. A data set is used to illustrate the usefulness of the optimal robust estimators for the parameter of extreme value distribution.
