Subnational home market bias in Vietnam: Evidence from enterprise‐level data

This paper contributes to the home (market) bias literature where administrative or political borders limit trade across borders. Home bias is well documented at the national and subnational level. To sort out macro (e.g., location characteristics) and micro (e.g., enterprise characteristics) factors behind home bias, we use small and medium‐sized enterprise (SME) data from Vietnam. Using the fractional multinomial logit model, we find that the proportion of SME sales outside of their home markets is positively associated with enterprise size, age, number of business association memberships and the distance of SMEs' most important supplier. In contrast, the proportion of SME sales to neighbouring provinces is negatively associated with the share of SME production for final consumption. Besides enterprise‐level frictions, market characteristics matter too. The proportion of SME sales to customers in their home markets is negatively associated with home or neighbouring provinces' governance quality, while the proportion of sales to customers in neighbouring provinces is positively associated with these areas' governance quality. These suggest that good governance frees SME resources for use in selling to less familiar markets.     

乌鲁木齐市建设用地对经济增长的贡献及Logistic曲线极限点估计研究

[目的]为提高乌鲁木齐市各生产要素的利用效率,明确经济发展模式,同时也为促进土地资源节约集约利用提供科学依据。[方法]基于C-D生产函数,以2005—2015年乌鲁木齐市统计数据为样本,借助EViews6.0和SPSS20.0软件测算出建设用地对经济增长的贡献率以及Logistic曲线极限点。[结果](1)资本投入要素对经济增长的贡献率(56.72%)最大,建设用地投入要素贡献(32.81%)次之,然后是劳动力投入要素贡献(13.25%),技术进步投入要素贡献(-2.78%)最小,但拥有很大的挖掘空间;(2)建设用地对经济增长的Logistic曲线极限点位于第二、三产业产值为1 522亿元处,对应2011年产值,2005—2011年建设用地对经济增长的贡献呈递增趋势,2011年之后贡献速度呈递减趋势,逐渐趋于平缓。[结论]建设用地对经济增长的驱动作用是有限的,只有通过技术创新才能实现经济发展模式由"依资本型"向"技术驱动型"转变。     

A Multicriteria Approach for Modeling Small Enterprise Credit Rating: Evidence from China

ABSTRACT

As the engine of China’s economy, small enterprises have been the central to the country’s economic development. However, given the characteristics of the small enterprises loan (i.e., short borrowing period, large volume, small amount and incomplete information), it is extremely challenging for financial institutions to assess their creditworthiness. Thus, it seriously delays and restricts the financing access for small enterprises. In an attempt to relieve the financing difficulty of small enterprises, this article makes use of 687 small wholesale and retail enterprises in a regional commercial bank in China, to establish a credit rating indicator system composed of 17 indicators by using both partial correlation analysis and probit regression. It then utilizes TOPSIS together with fuzzy C-means to score the credit ratings of our sample of small enterprises. With the dual test of default discrimination and ROC curve, the prediction accuracy of the established indicator system has reached 80.10% and 0.917, respectively, indicating the robustness and validity of our credit rating system.     

绍兴市土地利用时空变化研究

[目的]探讨经济发达地区土地利用变化时空规律,为城市发展提供合理土地利用政策,同时优化土地利用结构以支持经济可持续发展。[方法]通过遥感影像获取长时间序列的土地利用数据,探讨近30多年来绍兴市的土地利用变化,进一步利用土地利用动态变化模型,对绍兴市土地利用变化过程、趋势、变化轨迹进行了深入分析。[结果](1)绍兴市土地利用在1980~2000年相对稳定,在2000年后变化强度逐年增强,2005~2015年土地利用转化量增多和类型多样。绍兴市东北部平原和县区核心区域是经济发达地区土地利用变化的活跃区域,主要是其他类型土地向建设用地转移;(2)1980~2015年绍兴市土地利用变化轨迹主要受到人口增长和GDP增长的影响。[结论]城市化的发展和人口的迅速增长,使城市人口和土地面积迅速增加,造成城市边缘的农业用地转化成了建设用地。经济的发展、科技的进步及政府政策的制定,改变了人们的生活和工作方式,进而影响土地利用类型。     

Network ties and export propensity of Vietnamese small and medium enterprises

This paper investigates the impacts of different network ties on export propensity of Vietnamese small and medium enterprises (SMEs) in the manufacturing sector. Using data from a survey of over 2,600 manufacturing SMEs in 2015, we found that social networks contribute positively to the export propensity of SMEs, while the size of business networks negatively associates with the likelihood of export. However, bank networks and political networks are not significant for the propensity to export of Vietnamese SMEs. We discuss the results in detail and offer recommendations for SME owners, managers and policy makers.     

Bank lending channel in a dual banking system: Why are Islamic banks so responsive?

We examine the interest rate sensitivity of both deposits and credits at Islamic and conventional banks in Turkey. We find that the bank lending channel is especially operative for Islamic banks. Impulse responses for conventional and Islamic banks reveal that Islamic bank depositors’ sensitivity to policy rate changes is substantially larger than that of conventional bank depositors. Next to heavily dependence on deposit funding, we consider that inertia in Islamic bank deposit rates impedes these banks to keep those depositors who consider the opportunity cost of monetary policy rates is unbearable. On the lending side, we obtain similar results, implying that tight monetary policy leads to a larger contraction in Islamic bank credits. This finding is a reflection of the favourable attitude of Islamic banks towards small and medium‐sized enterprise (SME) financing. When similar relationships are analysed for currency and inflation shocks, we again find larger responses for Islamic banks showing the cyclical nature of SME credits.     

创业型中小企业财务管理的创新与应用研究

在国民经济高速发展的推动下,我国经济市场环境越来越好,企业的发展空间逐渐扩大。因此,诞生了很多创业型企业,在我国的经济活动中扮演着十分重要的角色。但是创业型企业由于经营经验少、管理制度缺失以及组织结构不完整等,在财务管理方面存在一些问题亟待解决。基于此,论文从创业型中小企业入手,对财务管理的问题、创新及应用策略进行了研究,以供参考。     

Do networks or performance impact the promotion of Chinese officials? Evidence from prefecture‐level cities

This study examines the effects of connections and economic performance on the promotion of Chinese city mayors. Our study differs from the published literature in four respects. First, this study covers a comprehensive data set, including 1,422 mayors from 284 prefecture‐level cities. The use of a large data set helps resolve mixed results of past studies. Second, we use a broader range of top leaders. Third, we apply a more comprehensive definition of connections than earlier studies. Finally, we examine the effects of the policy shift of the 11th 5‐year plan on promotion of mayors. Our results reveal that the performance of a city mayor assisted his/her promotion to party secretary before 2006 but not afterwards. However, a mayor's connection with five types of top leaders is helpful. Among the four types of connection, colleagueship is the most effective in expediting the promotion of mayors. Graduating from the same university and department is also helpful but to a lesser extent. Township connection is not useful.     

乌鲁木齐土地利用碳排放强度时空演变研究

[目的]土地利用二氧化碳排放强度是土地低碳利用的重要指标,对其时空调控是协同促进城市二氧化碳排放总量达峰的重要路径。[方法]文章研究基于乌鲁木齐市2005年和2012年1km高空间分辨率排放网格数据(CHRED)和土地利用矢量数据,采用GIS空间分析法,探讨乌鲁木齐市7个城区土地利用二氧化碳排放强度的时空演变特征。[结果](1)从时间上看,乌鲁木齐市7个城区的土地利用变化整体表现为"5增2减"的现象;二氧化碳排放总量从3 431.49万t上升到5 147.96万t,其中以城镇村及工矿用地二氧化碳排放增长最大,由2005年的2 885.15万t增加到2012年的4 139.15万t。(2)从空间上来看,城市向北部和东南部扩展明显,未利用地和耕地迅速减少,城市扩展区的二氧化碳排放量有明显增加;中心城区和城市扩展区二氧化碳排放强度上升最快。(3)从土地利用转移上看,土地利用结构的变化明显,整体呈现草地、耕地和未利用地向城镇村及工矿用地、交通用地、园林地和水域等类型转移。草地、耕地和未利用地向城镇村及工矿用地转移导致的碳排放强度增长最显著,均超过700万t/万hm~2。[结论]绿洲城市不同的土地利用类型二氧化碳排放强度时空差异较为显著,其中城镇村及工矿用地扩张是导致二氧化碳排放增长的主要原因之一。因此,合理控制绿洲城市扩张规模,优化城市用地布局,建立土地利用二氧化碳排放强度核算体系与综合调控政策,将是促进低碳城市建设的重要路径。
