运用超效率SBM-DEA模型对2008—2017年广西12个地市蚕桑产业生产效率进行测算,在此基础上运用面板Tobit模型对广西蚕业生产效率的影响因素进行初步探究.结果表明,广西蚕桑产业生产效率的整体水平偏低;财政支农、蚕茧收购价格、蚕农协会农户数、桑园规模对蚕桑产业生产效率具有正向相关性,养蚕收入和农村居民纯收入对蚕桑产业生产效率具有负向相关性.建议推行技术导向和规模导向型的政策,稳定蚕茧收购价格,制定蚕种投入量与桑叶产量技术标准,推行蚕桑业种养分离模式,优化财政支农支出结构.

Regional economic inequality is an inevitable phenomenon in economic development,as well as a common concern all over the world.The importance of regional economic inequality issue in the inland provinces of western China has been growing especially under the background that China is accelerating its inland opening/development and Western Development Program in recent years.This study,taking Chongqing as a typical inland region in western China,employs Gini,Theil index and coefficient variance to evaluate the regional economic inequality in Chongqing and its variation from 1994 to 2014.We then decompose Gini index in Chongqing into county (or district) level.Using county level regional economic inequality as dependent variable and choosing 15 independent variables in 4 categories (social factor,economic development,geographic location and transport,and policies),we apply ridge regression and geographical weighted regression models to examine the influence of these factors on regional economic inequality in Chongqing from the "global" and "local" perspectives respectively.The findings are as follows:(1) the dynamics of regional economic inequality in Chongqing can be divided into four phases with the event of setting up as direct-controlled municipality,the launch of new-type industrialization scheme and the Financial Crisis as critical time points.Such inequality over the past decades has always fluctuated between 0.3 and 0.4,which is quite close to the warning line (Gini =0.4) especially after the Financial Crisis;(2) the result of ridge regression shows that,among 15 factors,urbanization,industrialization,the endowment of labor resources,non-marketization,topography and preferential policies are the most significant factors which enlarge regional economic inequality;(3) the result of geographical weighted regression shows that,urbanization,non-marketization,industrialization,the endowment of labor resources and preferential policies contribute to regional economic inequality in Chongqing and the impact shows spatial heterogeneity.By contrast,the influence of topography is insignificant.The study analyzes the possible reasons and put forward some policy solutions.We hope that the research can contribute to the literature on the regional inequality issues in the study region and that the suggestions have some practical value for the rational and sustainable development in China's inland region.

Taking CNKI as the main data source from which we obtain relative documents from 1992 to 2014, this paper uses bibliometrics methods to examine the present situation and the development of research on regional development strategy of China. Speciifcally, we analyze the distribution of the research institutions, researchers, key words and periodicals according to EXCEL and UCINET software. The measuring results show that the number of annual papers changes like a “S”-shaped curve as the time goes by; the distributions of periodical doesn’t show with a characteristic of concentration, but with a tendency of economics and geography subjects. Institute of Geographic Sciences and Natural Resources Research, Wuhan University and Peking University are the main institutions of publishing papers. Hot spots of research focus on regional policy, the theory of the regional development strategy, regional differences, and the practice of regional macro strategy respectively.

Interaction between urban land use and urban transportation has been a research hotspot in the ifelds of Geography, Economics and Urban Planning. This article gives an overview on the studies of urban land use and transportation interactions, both domestic and abroad. Base on the review, we found that:For the impact of urban land use on urban transportation, most researches get to the same conclusion that high-density development decrease the dependency on private cars, but this is not the case for the impact of mixed land use on transportation;besides the scale of the researches on the impact of land use pattern on transportation generally differs, researches abroad tend to focus on a plot scale while that in China focus on city scale;for the impact of urban transportation on urban land use, researches domestic and abroad show little difference in the research point of interest and methodologies, but the wide-spread of high-speed rail in China does provide a new context for related studies;integrating both impacts into a model is a hotspot in this area, and researches abroad tends to develop the land use and transportation integrated model, while that in China generally involve a land use and transportation coordination assessment. This article thus highlights some future prospects for further research.

我们选取我国2003-2010年东、中、西部地区的面板数据,对房地产需求和供给收入弹性、房地产市场需求和供给及影响房价的因素、房地产对经济增长的作用进行实证研究发现,西部地区房地产市场的需求和供给收入弹性小于东、中部；房地产价格在需求和供给市场违背一般价格规律；银行信贷对东部地区房价的影响较为明显；中、西部当期需求的增加会促进下一期经济发展.

<正>房地产作为国民经济的支柱行业,一方面与宏观经济紧密相连,具有明显的周期性;另一方面属于资金密集型行业,与金融体系关系密切。过去十几年,我国房地产市场快速发展,房地产信贷规模也不断攀升。目前,我国房地产市场处于复杂的宏观调控期,尽管当前房地产贷款的

2010年9月底,国务院继4月份新政后对房地产市场存在回暖迹象的部分城市进行二次调控,效果却不理想。本文综合分析德国稳定房地产市场和新加坡治理房地产泡沫的成功经验,以及日本上世纪90年代房地产泡沫破灭的教训,结合国内经济发展和金融市场背景,提出房地产市场需要脱离支柱行业的产业转型、构建充足保障安居房并制定完善的分配制度、建立完善的风险预警机制、实行分税制以抑制投资性需求、兼顾中产阶级购房问题等方面的政策建议。

在日益增加的多方当事人争议中，仲裁解决纠纷的能力相对于诉讼而言是颇为有限的。因此合并仲裁作为完善办法之一，其提出有一定的社会实践意义。本文通过对合并仲裁的利弊进行分析，认为合并仲裁有其存在的价值和一定范围内的可行性，并从理论上进行了探讨和论证，以此作为以仲裁方式解决多方当事人纠纷的一种思路。
