区域文化对市场经济环境形成的影响研究

区域文化对市场经济环境的形成具有重要的作用。在深入分析区域文化对市场经济环境形成作用机理的基础上,结合我国区域经济发展实际,从政治文化对政治体制变革的影响,经济文化对经济组织创新的影响,伦理文化对竞争环境建立的影响,以及宗教文化对科学意识培养的影响等四个方面,论述了区域文化对市场经济环境形成的作用路径,说明区域文化对市场环境的形成具有内源性的影响。     

Intermediary asset pricing in commodity futures returns

This paper assesses the extent to which intermediary capital (IC) risk contributes toward explaining commodity futures returns. We find that the IC effect is substantially positive and continues to grow as the financialization of commodities deepens. Positive and negative IC risks play asymmetric roles, with the effect of negative IC strengthening in recent subperiods. We further confirm the heterogeneous roles of IC across individual commodities by cross-section analyses. Overall, the effect of the positive IC risk factor varies significantly. Portfolios with low basis, low open interest, low momentum, and low liquidity earn significantly higher returns than counterparty portfolios.     

Invisible costs in offshoring services work

Offshoring service work is an accelerating trend. While the cost-savings from offshoring service work are usually clear, operating at a distance also brings with it certain “invisible costs.” We combine existing service operations theory with insights from the literature on communications and culture to present a new conceptual framework, organized around interaction intensity and interaction distance. We identify the drivers of these costs. We conclude with recommendations for controlling or attenuating invisible costs in offshoring service work.

承运商的评价及选择,直接关系到供应链中跨国制造企业的运作成本,影响到企业的市场竞争力。因此,研究承运商的评价与选择方法,具有重要的理论意义和实践意义。文中提出了一种基于投入产出效率的承运商绩效评价模型,并应用该方法对某跨国制造公司承运商的评价选择进行了实例分析。     

Agriculture and aggregate productivity: A quantitative cross-country analysis

A decomposition of aggregate labor productivity based on internationally comparable data reveals that a high share of employment and low labor productivity in agriculture are mainly responsible for low aggregate productivity in poor countries. Using a two-sector general-equilibrium model, we show that differences in economy-wide productivity, barriers to modern intermediate inputs in agriculture, and barriers in the labor market generate large cross-country differences in the share of employment and labor productivity in agriculture. The model implies a factor difference of 10.8 in aggregate labor productivity between the richest and the poorest 5% of the countries in the world, leaving the unexplained factor at 3.2. Overall, this two-sector framework performs much better than a single-sector growth model in explaining observed differences in international productivity.     

太行山区商贾驿站型乡村聚落研究——以山西省平顺县花园村为例

"太行八陉"自战国时期便是连接太行山东西晋冀豫三省的通衢要道,特殊的地理环境形成了特殊的职能需求,从而造就了诸多因古道而生的山地商贾驿站式乡村聚落,作为一种特殊的传统村落类型,具有极高的历史文化和学术研究以及保护利用价值。山西省平顺县花园村可考历史逾500年,村落传统格局保存完整。仅有十四家住户的村落内曾建有寺庙四座,现存古碑14通,明代石桥一座,三股泉水伴生的石槽水利系统历经数百年,贯穿整个村落,整体形态凝练了我国乡村聚落营建的传统智慧。以花园村为例,对此特殊聚落类型进行了深入研究。     

Childcare Assistance: Are Subsidies or Tax Credits Better?

We evaluate price subsidies and tax credits for childcare. We focus on partnered women's labour supply, household income and welfare, demand for childcare and government expenditure. Using Australian data, we estimate a joint, discrete structural model of labour supply and childcare demand. We introduce two methodological innovations – a more flexible quantity constraint that total formal and informal childcare hours are at least as large as the mother's labour supply and the explicit inclusion of maternal childcare in the utility function as a proxy for child development. We find that tax credits are more effective than subsidies in terms of increasing average hours worked and household income. However, tax credits disproportionately benefit wealthier and more educated women. Price subsidies, while less efficient, have positive redistributional effects.     

The effect of domestic and foreign trade coordination on technological innovation: complements or substitutes?

Based on the theory of technology spillover in international trade, this paper discusses the technological innovation effect of trade by taking the influence of domestic trade into account. Under the constraint of the production possibility frontier, there is either complementarity or substitutability between domestic and foreign trade. It must be decided whether resources should be concentrated in one of the sectors (trade specialization) or instead allocated equally (trade equalization) between the two sectors. This paper firstly discusses how domestic trade and foreign trade work together to influence technological innovation, and how trade equalization and specialization affect different types of innovation. Using a provincial-level panel dataset from 2007 to 2015 in China, this paper constructs the indicators of domestic and foreign trade linkage and examines the impact of trade on innovation. The findings show that trade equalization mainly promotes incremental innovation, while trade specialization improves radical innovation. Thus, in the area of incremental innovation, attention should be paid to the equalized development of domestic and foreign trade, while in areas pursuing radical innovation, emphasis should be put on the specialization of the trade sector, avoiding equal allocation of resources to the two sectors.     

社会保护底线支出、城镇偏好与城乡居民收入差距

本文运用1999-2013年的省级面板数据,采取系统GMM估计方法考察了社会保护底线支出、城镇偏好与城乡居民收入差距之间的关系。不管是用人均指标还是占比指标来衡量社会保护底线支出水平,实证结果均显示,随着社会保护底线支出水平的不断提高,城乡居民之间的收入差距也在不断缩小。从各分项支出来看,低保支出、义务教育支出以及医疗卫生支出与城乡收入差距之间均呈显著负相关关系,但引入城镇偏好因素后,低保支出对城乡收入差距影响不再显著,而义务教育支出、医疗卫生支出的影响也有所减弱。
