经济新常态下金融包容与产业结构转型——基于中国省级面板数据的分析

在经济新常态背景下,产业结构面临重大调整,金融包容的融入,使中小企业或个人能够获得价格合理、方便快捷的金融资源,扶持创业创新发展,形成新的增长动力。本文基于1995～2012年中国31个省市的相关数据,运用面板数据模型和分位数回归方法,深入探讨金融包容对产业结构转型的影响。结果表明,金融包容与产业结构转型具有显著的正向关系,并且在不同分位点上金融包容水平对产业结构转型表现出较强的解释力,随着产业结构向高级化发展,金融包容在产业结构转型升级中的作用逐步凸显。经济增长、教育发展、财政支出规模和城市化水平均对产业结构转型具有促进作用,而过多的物质资本投入不利于产业结构转型。     

人体下肢运动能力测评研究

人体在短距离奔跑及跳跃时,足底压力的大小并不仅仅和体重相关,还反映了下肢运动能力的强弱。为了能够客观评价下肢的运动能力,设计了一套测试系统。采用压力传感器对足底压力进行测量,数据通过单片射频收发器件NRF24L01无线模块传输到微机中,记录下不同测试条件下的压力峰值。实验采集了12位测试者在慢走、快跑时的足底压力,分析了足底压力峰值与体重之间的关系。结果表明:压力峰值与体重的比值较小的人,下肢运动能力较弱一些;压力峰值与体重的比值较大的人,下肢运动能力较强一些。根据测评结果,可对人们的身体素质提升提出相关建议,对处于成长期的青少年尤为重要。     

An efficiency analysis of Swedish employment offices

In this paper the method–production frontier analysis is used to analyse differences in efficiency between different Swedish Employment Offices. Earlier empirical labour market policy evaluation studies have utilised various measures that, however, do not take into consideration differences between organisation units. The main result of this investigation is that employment offices show major differences in the efficiency with which they carry out their job matching services.     

Financial components of FDI and choice of capital structure: an analysis for 30 OECD countries

Even though the choice of capital structure depends on the three different financial components of foreign direct investment (FDI), previous research has regarded FDI as unidimensional rather than multidimensional. This study addresses new findings in the FDI area and investigates the relevant determinants of capital structure in 30 OECD countries from 2006 to 2014 within the framework of a simultaneous equation model. Our primary findings reveal that each component has its own deterministic features driven by relevant policy variables and risks in the market. While an increase or decrease in equity capital shows the ability of the host country to attract new investments, the subsequent components are mostly used to adjust the equity capital investment exposure.     

Firm heterogeneity and immigrant wage assimilation

This article investigates the role of job mobility in immigrant wage assimilation. I use longitudinal linked employer–employee data for Portugal to estimate the immigrant wage catch-up in log wage regressions with both individual and firm fixed effects. I show that moving to firms with higher wage premiums accounts for approximately 30% of the immigrant wage catch-up in the first years.

Trades and Quotes: A Bivariate Point Process

This article formulates a bivariate point process to jointlyanalyze trade and quote arrivals. In microstructure models,trades may reveal private information that is then incorporatedinto new price quotes. This article examines the speed of thisinformation flow and the circumstances that govern it. A jointlikelihood function for trade and quote arrivals is specifiedin a way that recognizes that an intervening trade sometimescensors the time between a trade and the subsequent quote. Modelsof trades and quotes are estimated for eight stocks using Tradeand Quote database (TAQ) data. The essential finding for thearrival of price quotes is that information flow variables,such as high trade arrival rates, large volume per trade, andwide bid–ask spreads, all predict more rapid price revisions.This means prices respond more quickly to trades when informationis flowing so that the price impacts of trades and ultimatelythe volatility of prices are high in such circumstances.
