高技术制造业与高技术服务业协同集聚的经济增长效应

基于中国省级面板数据，利用空间面板模型和面板门槛模型，探究高技术制造业与高技术服务业协同集聚的经济增长效应。结果表明：区域间产业集聚特征差异显著，高协同集聚主要集中在东部沿海地区，低协同集聚主要集中在西部地区。经济增长水平、高技术制造业与高技术服务业协同集聚水平均具有显著空间正相关性，二者协同集聚有助于促进区域经济增长。协同集聚的经济增长效应存在双重门槛，当高技术制造业集聚度和高技术服务业集聚度均介于第一、二门槛之间时，产业协同集聚的经济增长效应最强。仅少部分省域两产业集聚度介于第一二门槛之间，能够有效发挥协同集聚对经济增长的推动作用。     

Consumer cooperatives as an alternative form of governance: The case of the broadband industry

With a growing number of consumer cooperatives in non-agrarian industries such as energy and broadband, there is a need to better understand their emergence as a viable form of governance. In this context, the paper uses Mikami’s (2010) model on consumer cooperatives to explain their emergence as a result of their ability to generate additional equity financing through the membership market. It focuses on the motivations of consumers to financially contribute to a cooperative by examining the risks and benefits associated with the investment. Based on a survey of 759 consumers, it links their motivations for joining a cooperative to different forms of risks and benefits associated with the investment. It shows that the risks related to cost sharing and switching costs are important determinants for consumers. Other factors that affected the likelihood of joining a cooperative were expected benefits with respect to user network externalities and infrastructure gains.     

我国最低工资政策的就业效应——基于北京市和重庆市建筑业的分析

VAR模型对最低工资就业效应的分析结果显示:北京市的最低工资标准与建筑业就业只是在数理统计上存在关系,并没有实际的经济意义;最低工资对重庆市建筑业的微弱负影响可以忽略不计。最低工资的就业效应并不明显,可以紧密联系行业平均工资来调整最低工资标准,以保障劳动者的基本生活。     

高技术服务业与资源型产业融合对资源型企业两阶段创新效率的影响

基于新技术与新知识的高技术服务业跨界融合是传统企业实现创新资源优化配置、创新研发和商业转化的重要因素。因此，运用熵指数测度全国各省区高技术服务业与资源型产业融合水平，并利用2014—2017年资源型上市公司面板数据检验两大产业融合对资源型企业两阶段创新效率的影响，同时探讨企业吸收能力的调节作用。结果表明：现阶段高技术服务业和资源型产业融合程度不高，但发展态势良好，处于从失调走向协调的转变期；产业融合对资源型企业创新研发效率短期无显著影响，长期存在抑制作用，资源型企业技术能力刚性导致对新技术的排斥，且较大的产业间认知差距削弱了产业间良性互动带来的技术扩散效应；产业融合对创新转化效率呈先抑制、后促进效应，就长期而言，产业融合具有良好的创新转化推动力；资源型企业吸收能力分别在产业融合与滞后一期创新研发效率及滞后三期创新转化效率的关系中起正向、负向调节作用，表明资源型企业吸收能力构建尚不全面。     

要素价格扭曲、行业异质性与R&D投入关系研究——来自中国制造业28个细分行业的证据

从中观视角研究要素价格扭曲对制造业R&D投入的影响及行业差异，厘清行业异质性背景下要素价格扭曲影响R&D投入的理论机制，运用制造业细分行业数据，结合非线性面板门槛模型进行深入分析。结果显示：要素价格扭曲对制造业R&D资本投入和R&D人力投入均均具有显著抑制效应，行业异质性因素在二者间发挥重要调节作用。进一步，运用面板门槛模型对行业异质性因素的作用进行探究。结果表明，行业特征因素如市场竞争、资本密集度、企业平均规模以及对外开放度在不同门槛值区间，要素价格扭曲对R&D投入的影响效应均存在显著差异。研究结论为全面深化市场化改革、提高要素资源配置效率、促进制造业自主创新转型升级，进而推动创新型国家建设具有一定启示意义。     

不同经济发展水平下创新要素对产业创新绩效的影响及政策启示

基于不同经济发展水平研究视角，选取新一代信息技术产业为研究对象，采用改进的Griliches-Jaffe知识生产函数模型，运用面板数据回归分析方法，利用《中国高技术产业统计年鉴》（2007-2017年）中电子及通信设备制造业统计数据进行实证研究，探究创新要素投入与创新绩效的关系。结果发现：对于新一代信息技术产业，在不同经济发展水平地区投入相同创新要素对创新绩效的影响存在一定差异，尤其体现在技术投入要素作用效果上。这就意味着，对经济发展水平不同地区使用相同的创新要素推动产业创新发展是低效的；不同发展水平地区有针对性地分配创新要素，对于实现创新要素最大效率、推动战略性新兴产业布局与发展尤其关键。最后，提出相应政策启示及建议。     

How reliable and consistent are subjective measures of welfare in Europe and Central Asia?

This paper analyses the reliability and consistency of subjective well‐being measures, using the Life in Transition Survey. Drawing on two life satisfaction questions with alternative scales, our results do not reveal substantial biases in accounts of life satisfaction due to framing. Subjective individual assessments of household relative income position, on the other hand, do not appear to be reliable predictors of objective poverty or wealth. We find that subjective relative income position is only weakly correlated with objective welfare measures. There are differences in evaluations of the household's relative standing across different household members, and these differences are correlated with respondent characteristics.     

The Spanish Textile Industry Sans ATC Quota Protection

The Spanish textile and apparel manufacturing sectors have been badly impacted by the global recession as well as the removal of quotas that were in place with the Agreement on Textiles and Clothing (ATC). This study employs a cost function to investigate the presence of scale economies and the interrelationships among inputs of domestic capital, labor, and intermediate goods as well as outsourced (imported) intermediate products for the Spanish textile industry in a global environment that has become increasingly competitive. While there is evidence of scale economies at low output levels, there is also some evidence consistent with diseconomies of scale at the highest output levels. All of the inputs appear to be substitutes for one another except for domestic capital and outsourced intermediate goods. An important finding is that the demands for both labor and domestic intermediate goods have become increasingly sensitive to the prices of outsourced inputs. The estimated coefficients of dummy variables indicate that reduced international trade restrictions have put downward pressure on unit cost for the industry in recent years. These results suggest that the Spanish textile industry and its domestic suppliers will be increasingly challenged by international competitive pressures.     

资源配置视角下战略性新兴产业基地建设决策过程研究

Herding behavior in the Pakistan stock exchange: Some new insights

This study attempts to examine the presence of herding behavior in the Pakistan Stock Exchange (PSX). The novel contribution of this paper is that it investigates the herding phenomenon from a large number of facets such as herding of firms towards market, herding of firms towards industry portfolios, herding of industry portfolios towards market, herding in mostly traded stocks and in large and small stocks, and herding in the crisis period. For this purpose, we use the herding behavior model of Christie and Huang (1995) on the daily closing prices data of 609 firms listed on the PSX from January 2004 to December 2013. Results show that individual firms do not herd towards market index, except when the market experiences a negative return of 5%. However, when we sort firms into small and large groups based on median market capitalization, results indicate that large firms show herding behavior in extreme market movements. Further, we find that firms in several industries herd towards their industry portfolios. However, we find weak evidence of industry portfolios herding towards the market. We also segregate the impact of financial crisis of 2008 from normal times. These findings support results of our baseline estimation.
