中国区域金融发展与经济增长——基于具生产的OLG理论及面板数据的实证分析

基于具生产的OLG理论以及我国2001—2016年31个省、自治区、直辖市的动态面板数据,分别采用差分GMM和LSDVC回归方法,从整体和区域的角度分析金融发展水平与经济增长之间的关系,结果表明：（1）金融发展水平与经济增长之间存在显著滞后的非线性效应,即滞后的倒U型相关关系,这说明可以通过适度调控金融发展来加快经济增长速度;（2）在东北和西南地区,经济增长与金融发展水平之间的关系并不显著,这表明东北和西南地区的金融发展对经济增长没有起到实质性的促进作用,且更易出现“资金空转”问题。     

The Role of Manufacturing-specific Technology in Determining the Composition of Hours Worked in Korea

Abstract

This paper investigates the role of manufacturing-specific and neutral technological changes in explaining the dramatic shift in hours worked from the manufacturing toward the service sector. The finding is that manufacturing-specific technological changes are the main contributor to the shift in hours worked while neutral technological changes seem to play only a minor role in explaining it.

Estimating the validity of administrative variables

Administrative data have become more important for both official statistics and academic research. One possible problem with such data is that they are biased and have a low validity. Although this problem is often mentioned in a qualitative respect, the validity is seldom quantitatively measured. This article presents a method to estimate the validity of administrative variables. By applying the classical test theory, the validity can be determined by using linked survey and administrative data which should measure the same concepts. This idea is elaborated with an empirical example in which the construct validity of age, gender, educational attainment and wages is determined simultaneously. A linear structural equations model with a measurement component is used to compute the construct validity. The analyses reveal that educational attainment and wages show some bias, but not higher than the bias found in the survey.

精细构造解释技术在吉林油田木101井区的应用

吉林油田从勘探转入开发,原有三维地震解释方法已经不能满足开发阶段布井的精度要求,需要进行地震资料的精细标定与精细构造解释。选择和应用了多井综合标定和合成记录综合标定、三维可视化数据校正等诸多国内外分析技术,一方面提高了地震解释工作效率,另一方面保证了时深转换及构造成图的精度,形成了一套满足开发阶段精度要求的解释和成图的技术方法。     

An integrated approach based-structural modeling for risk prioritization in supply network management

Supply networks are complex and suffer always from various risks. An effective supply chain management requires suitable strategies to mitigate them. In previous literature, there has been a range of research into risk in firms but little in supply networks. This can be explained due to the huge number of risk variables and their direct and indirect interrelations that may suffer all supply chain partners (firms). Therefore, for better risk mitigation, a risk prioritization step is vital. To this end, the purpose of this paper is to propose a new integrated approach based on two structural modeling tools. Firstly, interpretive structural modeling has been used to present a hierarchical model showing the interrelationships between the risk sources. Secondly, MICMAC analysis has been used to quantify and classify the risk variables based on their mutual influence and dependence. The objective is to ascertain the key risk variables and theirs relationships. These prioritized risk variables provide a useful tool to supply network managers to focus on those key variables that are most essential for effective risk management strategies. A real case study in food industry is provided in order to illustrate the application of the proposed approach. The findings may be useful to the practitioners in risk management and may also interest academicians, since the method used here can be applied in other areas of industrial management as well.     

全球主要货币外汇交易比重变化与趋势——BIS三年一度中央银行调查报告解析

2013年9月,国际清算银行发布了《三年一度中央银行调查报告——2013年4月全球外汇交易统计初步结果》。通过与历年报告比较分析发现,近年来,全球外汇交易量显著增加：主要贷币交易量变化各异;外汇交易向主要金融中心汇浆趋势明显;人民币离岸外汇交易量激增,虽已成为全球第九大外汇交易贷币,但与其他主要贷币相比,交易量仍然较小。上述变化与特点,对中国积极推进人民币跨境使用和建设上海国际金融中心具有重要参考价值。
