基于阶层线性模型的集聚经济实证分析

基于中国151个地级城市的制造业行业嵌套数据,运用阶层线性模型和集聚经济的间接估计方法,捕捉集聚经济行业维度不可观测的异质性,揭示集聚经济在行业与城市维度间的内在联系。实证结果表明:地方化经济在制造业中得到验证;行业层面的集聚经济不仅受行业自身特征的影响,而且深受行业所嵌套的城市经济社会环境的影响;城市异质性显著影响行业集聚经济。

The effects of exports on facility environmental performance: Evidence from a matching approach

This paper employs matching techniques to investigate the effects of facility export status on environmental performance. Using facility-level criteria air emission data in the US manufacturing industry, we find the industry-specific effects of export status on emission intensity, measured by emissions per value of sale. In some industries, there is consistent and robust evidence supporting the superior environmental performance of exporters relative to non-exporters in terms of emission intensity for all criteria air pollutants tracked. In other industries, we find weak evidence that exporters appear to have a higher emission intensity than non-exporters. This industrial heterogeneity in the effects of exporting on the environment is closely related to industrial characteristics including pollution abatement capital expenditure, trade costs, capital intensity and others.     

Exporting status and success in innovation: evidence from CIS micro data for EU countries

Using a large sample of micro data from four waves of Community Innovation Survey for EU member states, we investigate the relationship between firms’ export status and different sorts of innovation activities. We find systematically positive relationship between the two, whereby the strongest correlation is found in case of product innovation and the weakest in case of organizational innovations. While aggregate data show that innovation success is increasing in firm size, we find that exporting has the strongest effect on innovation in the medium-sized firms. We also explore cross-country differences in the impact of export status on innovation. Countries with a higher share of exports in GDP and greater share of spending on research and development generally display a stronger correlation between exporting status and innovation.     

集体林区资源异质性农户林业生产行为动态特征及差异研究——以湖南省为例

分别以商品林农户、公益林农户和兼有林农户作为研究对象,采用描述性分析从林业生产过程和投入产出两个维度客观揭示3类农户林业生产行为动态特征及差异。打破将林区农户作为同质整体的传统假设进行研究的结果表明:商品林、公益林和兼有林农户林业生产行为整体趋势比较积极,但在造林、管护、采伐行为及林业投入产出等方面存在明显差异。因此,建议通过政策引导、市场调剂等方式形成商品林、公益林差异化经营优势,确保农户利益的同时,更好的贯彻森林分类经营管理理念,维护国家生态安全。     

Stochastic Route Choice Equilibrium Assignment for Travelers with Heterogeneous Regret Aversions

Most route choice models assume that people are completely rational. Recently, regret theory has attracted researchers’ attentions because of its power to depict real travel behavior. This paper proposes a multiclass stochastic user equilibrium assignment model by using regret theory. All users are differentiated by their own regret aversion. The route travel disutility for users of each class is defined as a linear combination of the travel time and anticipated regret. The proposed model is formulated as a variational inequality problem and solved by using the self-regulated averaging method. The numerical results show that users’ regret aversion indeed influences their route choice behavior and that users with high regret aversion are more inclined to change route choice when the traffic congestion degree varies.     

Sustainable tourism development and residents’ perceptions in World Heritage Site destinations

Set in Malaysia’s Lenggong Valley World Heritage Site (WHS), this paper uses stakeholder theory to explore the heterogeneity of positive and negative perceptions among residents and their effects on residents’ support for and participation in sustainable tourism development. Data from 221 completed questionnaire surveys revealed heterogeneous negative perceptions across residents’ age, level of education and economic involvement in tourism. Moreover, residents’ positive perceptions had a positive effect on their support for and participation in tourism development. This study contributes to the resident perception literature by using stakeholder theory to conceptualise the heterogeneity of residents’ perceptions and by examining the effects of those perceptions on their support for and participation in tourism development in a rural WHS destination in the developing world. Furthermore, the findings of this study have practical implications for local authorities aiming to improve residents’ support and participation in tourism planning for sustaining tourism development.     

对外直接投资对小微企业的就业效应分析——基于企业规模异质性视角的实证研究

从企业异质性视角出发,系统地考察了大中型企业对外直接投资对母国小微企业就业的影响,并在阐明大中型企业OFDI对小微企业就业的影响机制之上,利用我国2001-2013年省际面板数据对理论分析的结论进行验证。研究发现：从总体来看,我国大中型企业对外直接投资对母国小微企业的就业具有显著的影响;从分地区估计结果来看,大中型对外直接投资对小微企业就业的影响存在空间异质性,在东部地区,OFDI对小微企业的发展影响显著为正,对于中部地区影响虽然依然显著,但其影响系数明显降低,而西部地区的影响则显著为负;地区的金融发展水平在大中型企业OFDI对母国小微企业就业的影响中起到重要的调节作用。     

The contribution of vacations to quality of life

The contribution of vacations to people’s life satisfaction and Quality of Life (QOL) has recently attracted substantial attention among tourism researchers. Yet, most QOL scales do not include vacations: 7% explicitly measure vacations whereas 42% only include items relating to vacations within the broader Leisure domain. Leisure and vacations, however, differ substantially in nature with leisure referring to regular home-based activities and vacations being infrequent leisure activities away from home. As a consequence of the common amalgamation of vacations with leisure, there is limited knowledge about the specific contribution of vacations to people’s QOL. The present study (1) presents empirical evidence for the contribution of vacations to QOL, (2) determines the extent of this contribution, and (3) investigates variation in the extent to which vacations contribute to the QOL of different people. Results indicate that vacations contribute to the QOL of the majority of people, are as important a QOL domain as Leisure and People, and that QOL means different things to different people at different points in their life, representing an individual and dynamic concept.     

社会认同理论视角下的企业创新绩效前因组态研究

创新是企业竞争优势的重要来源,也是企业可持续发展的关键动力。探究企业创新的影响因素及其作用机制对于企业创新发展具有理论价值和现实意义。基于社会认同理论,本研究建立包含团队断裂带、团队异质性、环境不确定性以及企业声誉等要素在内的企业创新影响机制模型。通过对66家电子信息企业样本进行模糊集定性比较分析,本研究探究企业内部结构与外部环境的各个要素对于企业创新的协同效应与联动关系。研究发现: 高企业创新绩效的驱动路径有三条,路径1强调在高环境不确定性、高企业声誉情境下,低高管团队学术背景异质性及低断裂带距离有利于实现高企业创新绩效;路径2强调在高环境不确定性、高企业声誉情境下,高团队学历异质性与低断裂带强度有利于实现高企业创新绩效;路径3强调在高环境不确定性、低企业声誉情境下,高团队断裂带强度与低团队断裂带距离有利于实现高企业创新绩效。研究结果拓展了社会身份理论在企业创新领域的应用,也为企业创新绩效的提升提供了新的思路。
