我国城乡一体化的动力体系研究

城乡一体化是新形势下解决“三农”问题的根本途径,对深入贯彻落实科学发展观有重要的现实意义。城乡一体化的动力机制是城乡一体化研究的核心,通过城乡一体化动力机制的研究,明确推动城乡一体化的各项动因,有助于制定推动城乡一体化的政策,为各地城乡一体化发展提供理论和实践指导。城乡一体化的动力机制主要包括产业发展、城乡利益差别、政府利益驱动、政府制度、信息化等,它们共同推动了城乡一体化的发展。     

我国国内市场一体化的影响因素分析——基于面板数据的检验

在使用价格指数法测算出我国国内市场一体化程度的基础上,本文实证检验我国国内一体化的影响因素。结果表明,地方保护倾向与国内市场一体化水平负相关;铁路营业里程增长与国内市场一体化水平正相关,公路里程增长与国内的市场一体化负相关;CAFTA建设对国内市场一体化具有显著正向作用,有利于推进国内区域经济协调发展;区域GDP差异加剧了地方政府本地市场偏好。这对我国促进国内市场整合与区域协调发展具有现实意义。     

Capital market integration in ASEAN: A non-stationary panel data analysis

Motivated by the establishment of ASEAN Economic Community (AEC) at the end of 2015, we examine saving-investment relationship in various subgroups of ASEAN to assess their capital market integration. The results from second generation panel unit-root and cointegration tests that account for cross-sectional dependence as well as estimates of long-run saving-retention rate provide some evidence of market integration in ASEAN. The analysis of short-run dynamics suggests that capital mobility in ASEAN during 1980–2014 appears similar to that in OECD countries during 1970–1999. More importantly, across different panel estimators and subgroups of membership, there is considerable heterogeneity among the member countries. The saving-investment association is very weak, thereby implying very high capital mobility, in more developed members such as Singapore, Malaysia, and Brunei; the association is very strong, implying very low capital mobility, for much less developed members such as Laos, Myanmar, and Cambodia. The results call for renewed effort to develop capital markets in less developed nations and integrate them with the rest of the membership in ASEAN. In this paper, we also address several major shortcomings of the original Feldstein-Horioka framework.     

论城市土地定级权重确定方法之——综合集成赋权法

影响土地质量的因素很多，但对土地质量的影响程度并不相同，只有通过因素权重的科学确定才能正确揭示土地质量差异。如何确定城市土地定级权重系数，是土地资源综合评价中的核心问题。本文在分析传统主观、客观土地定级因素权重确定方法和土地定级因素与土地质量之间的联系的基础之上，提出同时体现主观和客观信息的综合集成赋权法，介绍了应用综合集成赋权法确定土地定级因素权重的具体方法，对综合集成赋权法运用于土地定级因素权重确定的可行性进行了探讨。     

举家外出的农民工融入城市问题研究——对在北京务工的500个农民工家庭的访谈数据分析

本文对目前在北京就业的农民工融入城市的现状和程度进行了实证分析,分析数据来源于2004年开始的、每2年进行一次的、在京就业的500个“80后”农民工市民化程度的跟踪调查和入户访谈。在对2010年11月-2011年3月调研数据进行描述性统计的基础上,笔者选择了因子分析方法,量化分析了农民工融入城市的程度,得出了制度上的限制、流动就业的类型和个人的资源禀赋条件是影响农民工融入城市的主要因素的结论。     

Research collaboration model in academic social networks

ABSTRACT

This paper proposes a hybrid collaboration recommendation method that accounts for research similarities and the previous research cooperation network. Research cooperation is measured by combining the collaboration time and the number of co-authors who already collaborated with at least one scientist. Research similarity is based on authors’ previous publications and academic events they attended. A weighted directed graph is built to discover new collaborators by using direct and indirect connections between scientists. Moreover, a consensus-based system is built to integrate bibliography data from different sources. The experimental results show that our method improves the recommendation performances over other methods.     

A revisit on real interest rate parity hypothesis – simulation evidence from efficient unit root tests

A set of unit root tests are applied to test the existence of long-run real interest rate parity among the G-10 countries over the period 1971M1 to 2007M2. Rather than trusting the asymptotic distributions, this article uses simulation techniques to establish the small sample distributions of these tests, conditional on the stationary and nonstationary processes. The empirical results indicate that the tests have stable finite-sample sizes and higher size-adjusted powers such that the two estimated processes can be distinguished from each other. Thus, for six of the nine countries, their series are more likely to come from the estimated Autoregressive (AR) stationary process than from the nonstationary process. Noticeably, the testing results are rather different from those using the asymptotic distributions, in which only three countries support the real interest rate parity.     

Falling walls and lifting curtains: analysis of border effects in transition countries

Since McCallum's (1995 McCallum, J. 1995. National borders matter: Canada-US regional trade patterns. American Economic Review, 85(3): 615–23. [Web of Science ®] , [Google Scholar]) finding of surprisingly high border effects on trade between the US and Canada, there have been a number of studies on other parts of the world, and improvements made to the gravity model to measure this effect accurately. This paper suggests some other modifications to the model, and applies it to a region of the world that presents a distinctly interesting case. Changes in border effects of formerly socialist countries in Central and East Europe, and countries in the former Soviet Union are analyzed during 1976–2002 at country and sectoral levels, and also with respect to blocs of countries. A discussion on cross-country variations in border effects follows the computations.
