黑龙江省边境小额贸易发展对策研究

近几年来,国家和黑龙江省政府实施了一系列切合实际的措施,有效地遏制了黑龙江省边境小额贸易额的下滑和大起大落态势,但在边境小额贸易发展中还存在很多不稳定因素,其发展前景仍不容盲目乐观。虽然黑龙江省发展边境小额贸易有独特的地缘和交通优势、历史人文优势、公共关系优势、边境口岸通关优势、经济互补性优势、贸易结算优势,但同时存在着出口商品结构单一、出口商品科技含量低、质量差、＂灰色清关＂影响边境小额贸易长远发展、中俄两国差异影响边境小额贸易的正常发展等问题,黑龙江省应发挥传统商品优势,完善进出口商品结构,边境小额贸易企业应实施名牌战略,提高产品的科技含量,积极应对边境小额贸易中的＂灰色清关＂,建立健全相关机构,保障边境小额贸易有序发展。     

Is there a case for carbon-based border tax adjustment? An applied general equilibrium analysis

Concern that unilateral Greenhouse Gas (GHG) emission reductions could foster carbon leakage and undermine the international competitiveness of domestic industry has led to growing calls for carbon-based Border-Tax Adjustments (BTAs). This article uses a global general equilibrium model to assess the economic effects of BTAs and comes to three main conclusions. First, BTAs can reduce carbon leakage if the coalition of countries taking action to reduce GHG emissions is small, because in this case leakage (while typically small) mainly occurs through international trade competitiveness losses rather than through declines in world fossil fuel prices. Second, even though the economic effects of BTAs vary somewhat depending on how they are implemented, their welfare impact is typically small, and slightly negative at the world level. Third, and perhaps more strikingly, BTAs do not necessarily curb the output losses incurred by the domestic Energy Intensive-Industries (EIIs) they are intended to protect in the first place. This is in part because EIIs in industrialized countries make important use of carbon-intensive intermediate inputs produced by EIIs in other geographical areas. Another, deeper explanation is that EIIs are ultimately more adversely affected by the existence of a carbon price itself than by any international competitiveness losses. These findings are shown to be robust to key model parameters, country coverage, targets and design features of BTAs.

跨境电商综合试验区试点政策如何影响电商行业发展

理解政府政策对电商行业发展的作用效果,事关我国电商行业发展以及各级政府的正确决策。通过构建一个基于知识螺旋演化的概念模型,探究跨境电商综合试验区试点政策对电子商务行业发展作用的内在机理,并在此基础之上提出研究假说,然后采用双重差分方法对研究假说进行实证检验,检验结果表明：在剔除其他因素影响的条件下,跨境电商综合试验区试点政策的实施能够促进电商行业发展。进一步研究发现：试点政策对电商行业发展的促进作用存在城市异质性,即地级城市作用最大,其次为副省级城市,再次为省会城市。因此,政府在制定促进电商行业发展的相关政策过程中,应将政策重点放在电商行业发展水平尚待提高的地级城市(除副省级和省会城市之外),试点政策在这些城市的作用效果更大。另外,我国西部地区的政策重点应放在加强电子商务行业发展的配套设施建设,这样才能提高试点政策的作用效果。     

Tari–tax reforms and market access

Reducing tariborder="0">s and increasing consumption taxes is a standard IMF advice to countries that want to open up their economy without hurting government finances. Indeed, theoretical analysis of such a tariborder="0">–tax reform shows an unambiguous increase in welfare and government revenues. The present paper examines whether the country that implements such a reform ends up opening up its markets to international trade, i.e. whether its market access improves. It is shown that this is not necessarily so. We also show that, comparing to the reform of only tariborder="0">s, the tariborder="0">–tax reform is a less efficient proposal to follow both as far as it concerns market access and welfare.     

云南省沿边地区经济开放评价及对策——以德宏州为例

云南沿边地区是改革开放后我国内陆对外开放最早、最活跃的地区之一,开放度逐渐上升,但"综合边缘化"因素依然存在,经济社会发展仍处于欠发达水平及状况。本文将研究置于中国—东盟自由贸易区全面建设、新一轮西部大开发及云南桥头堡建设的大背景下,以德宏州为例,对云南沿边地区区际、国际等二重开放情况及特征进行研究,进一步探索沿边地区开放的路径及选择。

The Changing Nature of Border,Scale and the Production of Hong Kong's Water Supply System since 1959

This article investigates the making of Hong Kong's water supply system since 1959. It starts by assessing the perspectives provided by the regime approach and the political ecology literatures. The case of Hong Kong brings in ideas from border studies and draws attention to the changing nature of the border to explain socio‐ecological and scaling interactions. The case study maps the border relationship between China and Hong Kong (and Britain), and the political tussle between them over the control of water supply to the city in the late colonial period 1959–78, which resulted in the creation of a localized self‐sufficient water supply system in Hong Kong, and the consolidation of Hong Kong's scale as a colonial city‐state under British rule. It further explicates the change in the nature of the political border since 1979, and the processes by which Hong Kong abandoned attempts to strengthen its local supply, becoming dependent on supply from the regional Dongjiang water networks, as well as the transformation of its scale to become a subordinate of the larger political unit in subsequent years.     

我国跨境短期资本流动的成因结构分析：2005～2008——一个基于VAR模型的实证研究

本文利用2005年7月以来的月度统计数据,通过基于VAR模型的脉冲响应分析和方差分解分析,从实证意义上验证了国内汇率、利率、房地产市场和股票市场对跨境短期资本流动的现实影响作用,且诸变量中,以汇率和地产价格的影响力为相对最强。据此本文认为,为了有效应对短期资本跨境流动的问题,今后一个阶段,应合理引导汇率预期并努力维持房地产价格的相对稳定。     

产业集群与信息化

当代世界经济发展正在出现一种引人关注的空间模式,有人称之为产业集聚或产业集群,而构成产业集群的系统的基本要素是物质与信息。在集群中产业之间能量传递和交换的物质流与信息流是相互依存的,但两者在产业关联中的作用方向正好相左。由于数字和网络技术的飞速发展所带来的是信息和它的实物载体的分离。信息流的地位和作用迅速提高,使集群中的产业关联基础发生了从物质流为主向信息流为主导的根本性转变。
