中国入世后的宏观经济模拟研究——利用模型释疑贸易协定及其直接结果对中国经济的影响

We address the macroeconomic issues of China' s accession to WTO, using a Chinesemacroeconomic model. We produce and comment 5 individual shocks, giving a full picture of the relevantmacroeconomic mechanisms The direct consequences of WTO accession on quotas, tariffs, and pricesubsidies. Assembling these shocks, we get a balanced result, and limited evolutions apart from tradeexpansion.     

中国证券市场股价指数VaR研究

This paper compares the models in Predicting the VaR of stock price indexes in China. Our resultsindicate that the normal model usually underestimate the VaR when given probability is 0.01 or 0.02, andthe weighted normal model usually overestimate the VaR when given probability is 0.04 or 0.05. Thehistorical simulating model and Logistic distribution model are superior to normal model and to weightednomal model in predicting the VaR.

东西部地区财政支出的实证分析

This article analysed the scale, structure and effects of finance expenditure in western and easternregions of China from 1996 to 2000. The conclusion indicates that both ablolute scale and relative scale offinance expenditure in the two regions have increased. The western regions put the emphasis of financeexpenditure on infrastructure while the eastern regions on science and technology. Compared with easternregions, the problem of finance expenditure in western regions lies in the government expenditure washigher than normal level; the gap in science and education expenditure of every person between westernand eastern regions have been increasing. How to increase the effects of finance expenditure is the mainproblem which western and eastern regions must face, and this problem means more improtance to westernregions.     

Bootstrap方法在证券投资基金风险测量中的应用

 Bootstrap method will largely improve the accuracy of risk measurement, which be used to calculate the value at risk of securities investment funds. The application of the Bootstrap method with GARCH-based risk measurement model, not only consider the fund’s data auto-correlation and the time-variable variance characteristic, but also very well simulate the distribution of the residual. The theoretical analysis and empirical analysis indicate that this flexible parameter-nonparametric mixed risk measurement model can improve estimation precision of VAR.     

论生产函数调整模型

Cobb-Douglas production function is a nonlinear model which is most frequently used and can beenchanged into linear model. There is no doubt for the reasonability of this logarithm linearization. Thispaper gives an new proposition on the basis of deeper analysis that there is a defect with this linearization,hence adjustable production function model is proposed to eliminate it.     

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.     

关于一国统计能力建设的研究

First of all, the definition of the statistical capacity for a country was given in this paper. Based upon it, author discussed how to evaluate a country's statistical capacity both from input side and output side. A possible way of evaluating a country's statistical capacity qualitatively was given. Finally it discussed how to building-up statistical capacity for a country.     

金融中介发展与经济增长:中国案例研究与国际比较

Using the cointegration analysis technology and causality analysis technology, we discuss the relationship between financial interrediaries development and economic growth in China, Evidences from the multivariate VAR system show that (ⅰ)as far as the relationship between financial intermediaries scale and economic growth is concerned, what Robinson (1952) declared is right, "where enterprise lead finance follows"; (ⅱ) on the relationship between financial intermediaries efficiency and economic growth, the view of many endogenous economic growth models can be supported by China case.

In a common sense, a transforming process of industrial structure is the process of the economicdevelopment. Firstly, this thesis reviews the past and the current of the industrial development in thecentral China after the PRC was established. Secondly, The thesis deeply analyses the reasons thatindustrial development of Jiangxi province lays behind the others in the central China in six aspects assystem, investment, level of opening-up, and so on. Finally, after realizing Jiangxi's present situation andusing the successful experiences on industrial development of developed countries and areas for reference,we pose six suggestions and measures to focus on accelerting to deyelop economy and upgrade industrialstructure of Jiangxi Province.     

外商直接投资、产业关联与技术外溢

本文利用1999-2007年170多万家制造业企业数据,从企业异质性视角,研究了FDI通过水平关联和垂直关联等渠道对内资企业的技术溢出效应.本文的研究不仅回答了我国制造业企业是否存在FDI技术外溢,而且还深入研究了技术外溢效应是如何发生的.研究结果表明:①从总体上看,外资企业主要通过前后向关联效应促进本地企业生产率的提高,在行业内,存在市场挤出效应.②与私营企业相比,外资并没有通过水平或垂直关联对国有企业产生正的技术外溢效应.内外资企业之间技术差距越小,越有利于FDI技术外溢的产生.③外资的异质性会影响FDI技术外溢的效果,出口型FDI对内资企业存在显著的水平挤出效应,外资控制权越高,技术外溢的效应越弱.     

基于知识产权保护的国际贸易和FDI技术溢出效应研究

国际贸易和FDI是国际技术溢出的两个重要途径。文章通过岭回归分析方法实证研究得到,在开放经济条件下,我国现阶段的知识产权保护强度正处于对外贸和外资的技术溢出有正向效应的阶段,FDI对我国的知识产权保护制度的敏感度更高。国内R&D投入对技术进步具有显著的促进作用,同时在知识产权保护下国际技术外溢和扩散作用已经成为我国经济增长的重要外部推力。但现阶段我国知识产权保护强度仍然偏低,执法力度薄弱,削弱了我国对国外FDI技术溢出的吸收水平,影响了外资的技术溢出对我国技术进步的贡献。     

FDI对中国全要素生产率影响的两面性——来自空间维度的证据

虽然关于行业维度的研究大都认为FDI在发展中国家产生了显著技术溢出效应,但却忽略了FDI 在空间维度所产生的溢出效应.因此,引入样本截面区位信息,构建空间Durbin模型,实证检验FDI对中国Malmquist生产率的空间溢出效应.结果显示:FDI在区域内产生了正向溢出、在区域间产生了负向溢出,FDI空间溢出总效应弱化了全要素生产率;FDI溢出的空间辐射能力有限,仅对距离非常近的一阶邻域具有显著影响.     

FDI、金融市场发展效率与中国经济增长

金融市场是联接FDI技术外溢和经济增长的重要纽带,其效率的高低将直接影响到FDI技术外溢的效果进而影响到经济增长。通过理论模型分析和实证数据检验,本文认为,受"金融市场发展门槛"的限制,当前我国效率相对低下的金融市场,不能为FDI技术外溢效应的产生提供必要的金融环境支持,外商直接投资主要通过增加资本积累来促进我国的经济增长。     

经济政策不确定性是否降低了全球技术溢出强度:基于货物贸易与服务贸易的对比分析

本文采用20个国家及地区细分类型的货物贸易和服务贸易双边数据,对比研究不同贸易类型技术溢出对进口国全要素生产率的影响,并进一步分析出口国经济政策不确定性是否会降低技术溢出的作用强度。结果显示:一方面,货物及服务进口贸易引致的技术溢出显著促进了母国相对全要素生产率的提升,服务进口贸易技术溢出作用强度为0.0432,比货物进口贸易高77.8%,且两者作用强度经检验存在显著差异,这意味着服务贸易已成为全球技术溢出更为重要的载体;另一方面,加入经济政策不确定性指数后发现,各类贸易溢出仍能显著促进进口国相对全要素生产率的提升,但是经济政策不确定性显著降低了技术溢出作用的强度,服务进口的贸易技术溢出作用强度所受影响比货物进口高95.5%。本文的研究结果表明,适当对进口贸易结构进行纠偏,挑选经济政策不确定性较低的出口伙伴国是强化我国进口技术溢出吸收的关键。     

R＆D投资、FDI技术外溢与创新——基于负二项分布模型的分析

借助更加适合专利产出存在过度分布时的固定效应负二项分布模型,解决泊松回归模型处理专利数据时遇到的过度分布问题,分析了中国R＆D投资和FDI外溢对创新的影响以及这种影响的区域差异。研究表明,R＆D投资和FDI外溢对中国的专利申请数量都有显著的正向效应。从分地区的结果来看,东、中、西部R＆D资本投入效率不存在显著差异而FDI外溢差异较大,由于FDI在东部地区发挥的作用远远大于其它地区,FDI仍然在进一步扩大东部地区与内陆地区的技术差距。     

A Multivariate GARCH Model Incorporating the Direct and Indirect Transmission of Shocks

Theoretical models of contagion and spillovers allow for asset-specific shocks that can be directly transmitted from one asset to another, as well as indirectly transmitted across uncorrelated assets through some intermediary mechanism. Standard multivariate Generalized Autoregressive Conditional Heteroskedasticity (GARCH) models, however, provide estimates of volatilities and correlations based only on the direct transmission of shocks across assets. As such, spillover effects via an intermediary asset or market are not considered. In this article, a multivariate GARCH model is constructed that provides estimates of volatilities and correlations based on both directly and indirectly transmitted shocks. The model is applied to exchange rate and equity returns data. The results suggest that if a spillover component is observed in the data, the spillover augmented models provide significantly different volatility estimates compared to standard multivariate GARCH models.     

国际资本流动、对外贸易和金融发展对新兴经济体全要素生产率的影响

资本流动和对外贸易是新兴经济体融入外部经济的两种基本途径,金融发展是其重要的内部推动力。新兴经济体在全球化进程中将会面临怎样的难题？运用随机前沿生产函数对全要素生产率进行分析与评价,研究发现：资本流入、进口资本品与服务是新兴经济体技术溢出的重要途径,金融深化对其所带来的技术溢出起到了媒介作用;资本流动与贸易又推动了金融市场的发展,彼此之间形成了交互效应;新兴经济体的技术效率总体上呈现上升的态势,但在效率值上存在着明显差异。新兴经济体对国外资本、技术与市场存在着路径依赖,这已成为制约其持续发展所面临的共同难题。     

基于混频数据的实体经济与金融市场时变溢出效应研究

本文基于混频VAR模型分析了中国实体经济与股票市场、债券市场之间的时变溢出效应。结果显示,实体经济与股票市场、债券市场之间收益率与波动率的溢出效应呈现显著的时变特征,溢出效应在金融危机期间呈现快速上升趋势,而后呈现下降态势,且易受到极端事件的影响;在大部分考察时期内存在股票市场向实体经济的波动率溢出效应,而债券市场相对于实体经济则从考察初期波动率溢出效应的净输入方转化为中后期的波动率溢出效应的净输出方。进一步分析收益率与波动率总溢出指数的影响因素,结果发现,极端事件、宏观经济代理变量和期限利差对于溢出效应具有正向影响,泰德利差对波动率总溢出指数具有负向影响,而投资者情绪指数对收益率总溢出指数具有负向影响。     

房地产股票市场溢出效应研究

本文应用单变量GARCH模型和互相关函数探讨了不同市场之间的收益和波动的溢出效应;仿照收益的概念提出了“波动演进”,并使用向量自回归模型研究了波动和收益溢出的动态过程。研究发现,收益和波动的溢出存在地域特性,即同一地域的国家或地区之间存在快速且强烈的溢出效应。研究还揭示了一些国家或地区金融市场的特点,比如中国大陆是一个波动接受国,而德国是一个纯波动出口国。此外,通过比较平静时期和紧张时期的股市,可以观察到投资者的行为产生了变化,但是他们对信息的判断能力和速度并没有提高。
