从竞争到合作:中印能源关系析论

中国和印度作为两个新兴大国,又都是能源进口大国,在国际能源领域形成竞争关系在所难免。在中东、中亚—里海、俄罗斯及世界其他地区,中印展开能源竞争导致双方利益缺失。随着中印双边关系的改善,双方领导人做出了及时的政治判断,中印企业联手参与国际能源合作,正在实现由竞争对手向合作伙伴的身份转变。     

Tracking Distortions in Agriculture: China and Its Accession to the World Trade Organization

This article examines the impacts of China's accession to theWorld Trade Organization (WTO) on prices in its agriculturalsector. The analysis uses a new methodology to estimate nominalprotection rates in China's agricultural sector before its accessionto the WTO. These new measures account for differences in commodityquality within China and between China and world markets. Theanalysis shows that some of China's agricultural commoditiesare well above world market prices and others are well below.The article also assesses market integration and efficiencyin China. It finds high degrees of integration between coastaland inland markets and between regional and village markets.The remarkable improvements in market performance in recentyears mean that if increased imports or exports affect China'sdomestic price near the border, producers throughout most ofChina will feel the price shifts.

Trading imbalances,predictable reversals,and cross-stock price pressure

We test the implications of a multi-asset equilibrium model in which a finite number of risk-averse liquidity providers accommodate non-informational trading imbalances. These imbalances generate predictable reversals in stock returns. An imbalance in one stock also affects the prices of other stocks. The magnitude of the cross-stock price pressure depends on the correlations of the stocks’ underlying cash flows. The model implies that non-informational trading increases the volatility of stock returns. We confirm the model's implications using data from the Taiwan Stock Exchange.     

农户人力资本投资与农民收入增长

Based on an analysis of some theories, this paper studies the relationships among rural household investments and their interaction with farmer income increase empirically by the data of 1983–2005. The findings are: (1) Health investment makes against the growth of farmer, human capital investments for other types, besides, it can not satisfy the needs of farmer. (2) Although migration investment is useful to the growth of farmer income, education and health investment, its effects is time lagged. (3) Education investment has the biggest effects on the growth of farmer income; besides, it also reduces the cost of migration. However, this reduction is a bit small. Finally, some brief suggestions are put forward based on the analysis. __________ Translated from Jingji kexue 经济科学 (Economic Science), 2007, (3): 26–35     

制度环境、技术创新与传统产业升级

基于2008-2015年中国省际面板数据,构建门槛效应模型,将制度环境设为门槛变量,实证分析技术创新对传统产业升级的影响。结果发现,各区域制度环境差别会导致技术创新对传统产业升级表现出明显的门槛效应,即市场化处于较低水平时,技术创新对传统产业升级的作用不显著;伴随着市场化水平的不断提高,技术创新对传统产业升级的促进作用逐渐显现,并且促进强度呈倒U型结构。研究结论为传统产业升级提供了新理论视角,对如何更有效地通过技术创新促进传统产业升级具有重要指导意义。     

网络平台企业免费产品相关市场界定与案例应用——以视频平台为例

平台企业对单边提供免费品,使基于价格变动的SSNIP测试法无法用于判断相关市场。本文以视频平台为例,基于Filistrucchi双边市场测试法,通过将SSNIP测试法中对一边市场的产品价格提升替代为广告时长的增加,改进了基于价格变动的假定垄断测试法,构建了网络平台企业免费产品的SSNDQ模型。在此基础上分析了加入会员收入的情况。主要结论是：（1）虽然传统的SSNIP测试法不适用于免费产品,但是影响用户“注意力”的变量“广告时长”能降低产品质量,是SSNIP测试法中价格的有效替代变量。本文证明了改进的SSNDQ测试法具有一般性,并给出了基于SSNDQ测试法的相关市场判断条件。（2）给出了界定网络平台免费产品相关市场的思路和分析框架、平台付费化趋势下免费产品与付费产品共存状态下的情形,并推导出不同利润差结果下判断平台用户不同行为及相关市场范围的条件。基于这一方法的测试为并购审查和反垄断认定,提供了依据和证据。     

制造业投入服务化对碳生产率影响的理论建模和实证检验——以珠三角为例

制造业投入服务化有利于制造业提高劳动生产率,且具有生态效益。在短期内,制造业服务化的发展会引起碳生产率的降低;但随着制造业服务化发展到一定程度,服务化对碳生产率的负向影响转为正,促进制造业碳生产率的提高。碳生产率与制造业服务化之间存在非线性关系且呈U型。
