On the base of analyzing the shortcomings of produetion function, the author analyses the factors affecting the growth of productivity of China since the reform and opening up by using index method. The results show that 44.73% of the change of productivity is induced by the shift of employed persons between industries.     

我国外资利用的经济增长效应——基于内生经济增长模型的分析

The flowing of foreign capital is related with the economic security of one countries. The experiencesand lessons of many developing countries show that the impact of the foreign capital to the domesticeconomic is often the most important factors of the financial crisis. So it is important to a analysis theforeign capital economic growth effect. Based on the endogenous economic growth model, this paper firstdistricts the three cases of the foreign capital impact and give the three factors of the foreign capitalaffecting to the economic path. The using the sample data of China, we analyze the three factors. Theresults show that all the three factor effets are all positive, which means that the foreign capital utility ofChina is efficiency.

The researchers often discussed that how to get the value of the stock level of sub-soil asset by net present value(NPV) when they considered the value of depletion of natural recourse in the past. They did not pay more attention to elements which impact the value of the stock level of sub-soil asset. This article introduces a general formula, then focuses on the impact of each element changes on the value of stock level of sub-soil asset in terms of quantity, it gives an illustrative example at the end.

Uncertainty and sensitivity analysis techniques as tools for the quality assessment of composite indicators

Summary.  Composite indicators are increasingly used for bench-marking countries' performances. Yet doubts are often raised about the robustness of the resulting countries' rankings and about the significance of the associated policy message. We propose the use of uncertainty analysis and sensitivity analysis to gain useful insights during the process of building composite indicators, including a contribution to the indicators' definition of quality and an assessment of the reliability of countries' rankings. We discuss to what extent the use of uncertainty and sensitivity analysis may increase transparency or make policy inference more defensible by applying the methodology to a known composite indicator: the United Nations's technology achievement index.     

“免费”内容产品核算问题研究

近年来,伴随着数字化技术的快速发展,企业盈利模式不断创新,许多互联网企业通过向居民提供大量的免费或者价格低廉的内容产品来吸引用户,借助广告和其他业务实现盈利。“免费”内 容产品对生产统计、收入统计与消费统计等统计理论均带来了严峻挑战,使得居民福利与目前SNA框架下GDP测算之间的偏离越来越突出。“免费”内容产品核算问题成为国民经济核算面临的重要任务,联合国统计委员会明确将其列入SNA研究议程。本文对“免费”内容产品的核算问题进行了探索性研究,探析“免费”内容产品的概念和范围,系统梳理并剖析国际上“免费”内容产品核算方法的优劣之处,创造性地提出采用实物转移的思路来分析“免费”内容产品的运行机理,并基于国民经济核算视角设计“免费”内容产品的核算框架,最终从宏观层面对中国“免费”内容产品规模及其对名义GDP的影响进行了试算。本文的研究立足中国数字化转型的社会实践,为解决数字化转型带来的经济统计国际性难题进行了有益的尝试。     

中美贸易摩擦、美国进口冲击与中国企业创新

在中美贸易摩擦不断升级的背景下,基于高度细化的微观企业数据,本文实证分析了来自美国的进口竞争对中国企业创新的影响。研究发现：①从整体上来看,来自美国的进口竞争优化了企业的专利申请结构,对企业发明专利申请量具有显著促进作用,对企业实用新型专利和外观设计专利申请量无显著影响。②来自美国的进口竞争,对内资企业、低融资约束企业的创新总产出具有显著促进作用,创新总产出增加是由于高质量创新（发明专利）与低质量创新（实用新型专利、外观设计专利）同时显著提升导致的;外资企业、高融资约束企业的创新总产出下降是由于低质量创新显著下降、高质量创新变化不显著导致的,对低生产率企业高质量创新的促进作用大于高生产率企业。③来自美国的进口竞争增加了企业退出市场的风险,为了应对美国进口冲击,中国企业积极应对,增加研发投入支出、优化就业结构、扩大就业规模,加快高质量创新,从而产生了“逃离竞争效应”。     

进口需求函数选择及弹性分析——以美国苹果汁进口需求为例

运用2002年1月至2010年12月间,共108组美国苹果汁进口月度数据,比较分析Barten（1993）发展的一般化需求模型与其交错的四种可微分的需求模型,探寻和检验适合美国苹果汁进口需求数据资料的模型形式;对模型的加总性、齐次性、对称性、自变量内生性、需求系统的拟合优度进行检验,结果显示：一般化需求模型更符合数据资料。美国对中国苹果汁进口需求的支出弹性显著为正;受中国苹果汁自价格影响不显著;中国苹果汁对美出口的主要竞争国家是加拿大。     

Towards a unified definition of maximum likelihood

A unified definition of maximum likelihood (ml) is given. It is based on a pairwise comparison of probability measures near the observed data point. This definition does not suffer from the usual inadequacies of earlier definitions, i.e., it does not depend on the choice of a density version in the dominated case. The definition covers the undominated case as well, i.e., it provides a consistent approach to nonparametric ml problems, which heretofore have been solved on a more less ad hoc basis. It is shown that the new ml definition is a true extension of the classical ml approach, as it is practiced in the dominated case. Hence the classical methodology can simply be subsumed. Parametric and nonparametric examples are discussed.

The Multiplicative Definition of Interaction

The theory of the multiplicative definition of second order interaction is considered. Necessary and sufficient conditions in terms of the correlations in the marginal two-dimensional distributions are found for the existence of a “perfect” set of probabilities. Some progress is reported on the proof of the uniqueness of the multiplicative set of probabilities for a given set of two-dimensional distributions. The multiplicative property of such sets is preserved under pooling of marginal sets only in trivial cases, and so the multiplicative definition cannot be said to be a straightforward generalization from the definition of no interaction in two-dimensional distributions.
