Productivity Growth in the Chinese Economy by Industry and the Role of Foreign Capital

I. IntroductionIt is well known that China’s reform and open-up policy initiated in 1978 had an extremelylarge impact on the Chinese economy. This policy represented an about-face against thetraditional self-reconstruction strategy that China had maintained since the founding ofthe people’s Republic in 1949. Although China’s economy temporarily fell into confusionfor a few years after the Tian-an-men incident in 1989, China continued to record high GDPgrowth. Moreover, after Deng Xiao…

Saddlepoint approximations to the mean and variance of the extended hypergeometric distribution

Conditional inference on 2 x 2 tables with fixed margins and unequal probabilities is based on the extended hypergeometric distribution. If the support of the distribution is large, exact calculation of the conditional mean and variance of the table entry may be computationally demanding. This paper proposes a single‐saddlepoint approximation to the mean and variance. While the approximation achieves acceptable accuracy for ordinary practical purposes, an alternative saddlepoint approximation is provided that gives much closer to exact results. It improves the accuracy of current approximations to up to more than four powers of ten.     

外资影响我国出口产品质量的差异性研究:从一个地区市场化程度的视角

我国正在经历从出口成本优势向质量优势转型的重要时期。外资对我国出口产品质量的影响及其差异性成为政府和学界关注的问题。本文从市场化水平、政府与市场的关系以及知识产权保护等三个方面检验了制度因素对外资质量溢出的影响。回归结果表明:(1)市场化程度低确实抑制FDI质量溢出;(2)政府干预对外资质量溢出效应产生了负面影响。在低市场化程度或者高政府干预样本组中,FDI质量溢出效应不显著;(3)知识产权保护对FDI质量溢出的影响程度非常有限。本文的结论为政策制定者提供了决策参考依据。简政放权、降低企业面临的行政成本是促进我国本土企业改善其出口产品质量的重要抓手。     

Appropriate assumption on cross-hauling national input–output table regionalization

Input–output tables are useful for regional economic analyses. Although scholars often regionalize national input–output tables, cost-related issues make surveying regional trade flow difficult; hence, non-survey approaches are implemented instead. While location quotient (LQ) approaches have been used widely, they ignore cross-hauling in interregional trade. Therefore, alternative non-survey approaches with different assumptions on cross-hauling are used, such as cross-hauling depends on regional size and cross-hauling is proportional to its potential determined by output or demand. This study concludes that the most appropriate assumption, as per the relative performance of non-survey approaches, is that cross-hauling is in proportion to trade volume.     

Updating Input–Output Tables with Benchmark Table Series

Numerous methods have been proposed to update input–output (I–O) tables. They rely on the assumption that the economic structure will not change significantly during the interpolation period. However, this assumption may not always hold, particularly for countries experiencing rapid development. This study attempts to combine forecasting with a matrix transformation technique (MTT) to provide a new perspective on updating I–O tables. Under the assumption that changes in the trend of an economic structure are statistically significant, the method extrapolates I–O tables by combining time series models with an MTT and proceeds with only the total value added during the target years. A simulation study and empirical analysis are conducted to compare the forecasting performance of the MTT to the Generalized RAS (GRAS) and Kuroda methods. The results show that the comprehensive performance of the MTT is better than the performance of the GRAS and Kuroda methods, as measured by the Standardized Total Percentage Error, Theil's U and Mean Absolute Percentage Error indices.     

Estimation of interregional input–output table using hybrid algorithm of the RAS method and real-coded genetic algorithm

In this paper, we propose a method for improving the accuracy of the estimation of interregional input–output tables, by combining the RAS method and the real-coded Genetic Algorithm (GA); these are simple representative methods for the estimation of an interregional input–output table. By comparing the performance evaluation results obtained using the proposed method, the RAS method, and Simulated Annealing, we verified that the combination of the genetic algorithm and the RAS method can enhance the estimation accuracy of an interregional input–output table. In addition, performance is further enhanced by adjusting GA parameters.     

基于价值增值的比较优势研究

本文基于Hummels et al．（2001）的分析框架，利用OECD提供的投入产出数据库，计算并比较中国与其他29个主要经济体产品增值率指数及增值比较优势指数。实证结果显示，我国的比较优势产业主要集中在制造业，然而这些比较优势产业的增值率不仅低于服务业和农矿制造业，并大大低于同一产业的世界平均水平。     

全球价值链与国内价值链——基于投入产出表的新方法

价值链作为组织和协调经济活动的微观机制,已使经济全球化和增长模式发生了深刻的变化。本文利用来自投入产出表的新方法,测度了广东省和江苏省全球价值链和国内价值链的水平。结果表明,粤苏两省切入全球价值链的倾向高于切入国内价值链的倾向,而对其它省份关联效应较大的行业基本上是中间品行业,且具有自然资源密集的特征。全球价值链与国内价值链之间的互动关系,则关系到我国产业升级的前景和区域经济协调发展的基础。
