中国农村经济市场化指数——各地区的相对进程研究

农村是中国经济体制改革的起点,农村经济市场化是中国经济市场化的重要组成部分。中国市场化进程的不平衡性不仅体现在城乡之间,也体现在农村内部。从市场化的基本含义和基本要求出发,科学地设计农村经济市场化的各项指标并对之进行测算,进而了解各地农村经济的市场化相对进程和各经济指标之间相互关系对于建设社会主义新农村具有重要意义。     

我国整体及四大经济区域的金融安全评价指标体系的构建研究

随着金融业的发展,不断积累的金融风险将对我国的金融安全构成严重威胁,而金融安全是经济可持续健康发展的基础和重要保障。因此,有必要构建我国整体及各区域的金融安全评估体系。根据2011-2019年第三季度（共计35个季度）的数据,从宏观经济环境、财政和金融三个维度选取指标并运用熵值法进行赋权,对全国及四大经济区域的金融安全指数及其变化趋势进行了计算分析。研究发现：①观测期内全国金融安全指数在整体上呈持续下行趋势,尤其是在2011-2012年二季度间出现了大幅下降;②四大经济区域的金融安全指数在2011-2015年一季度间均呈下行趋势,在2015年二季度至2019年三季度间相对稳定但一直处于低位。研究表明,观测期内我国整体及各区域的金融安全水平都出现了令人担忧的下降态势,四大经济区域的金融安全指数变化走势均不同且呈现出区域差异性。

Real Geographies,Real Economies and Soft Spatial Imaginaries: Creating a ‘More than Manchester’ Region

This article develops a framework for analysing region‐building processes as spatiotemporal constructs, involving competing spatial imaginaries and attempts at consolidating these through institution building. Central here is the performative role of what we refer to as ‘soft space imaginaries’ in the ‘phased’ building of regions for planning and economic development over time. We demonstrate how this understanding can be used to examine the phased enactment of successive waves of region‐building by tracing the evolution of multiple soft spatial imaginaries in north‐west England. The analysis exposes the variable logics, alliances of actors, and tactics used to build momentum and secure legitimacy around preferred imaginaries which advocates often promoted on the grounds that they somehow reflected ‘real geographies’ or ‘real economies’. In this context, soft space imaginaries are seen to play an integral role in intellectual case making about the contemporaneous form and purpose of subnational governance. Yet our analysis also exposes the durability of past soft space imaginaries and their continued impact on efforts to build new soft spaces. What emerges is an understanding of soft space imaginaries as more than just superficial representations. They can help determine where government investment is channelled and into what kinds of policies.

欠发达地区新农村建设与农村公共产品供给

农村公共产品的供给对欠发达地区新农村建设意义重大，而现阶段欠发达地区农村公共产品供给却存在着供给观念滞后、供给主体单一、城乡之间供给的不公平性以及监督管理体制的缺失等突出问题。如何解决这些问题。主要应从转变观念、引入市场机制和社会力量、建立城乡一体化的公共产品供给体系、创新农村行政管理制度等方面入手。以此推动欠发达地区新农村建设的进程。     

产业集群、区域经济与金融深化——金融支持中国戴南产业集群发展模式研究

积极实施城市反哺农村，工业反哺农业，以工业化致富农民，城市化带动农村，产业化提升农业，是建设社会主义新农村的成功经验。金融作为现代经济的核心，是支持社会主义新农村建设不可或缺的重要因素。本文结合中国戴南产业集群发展的轨迹，剖析了戴南产业集群发展的现状、特点以及制约集群进一步发展的金融瓶颈，提出了金融支持戴南产业集群发展的构想，着重指出了转变观念、创新机制、组合产品、完善体系等四个方面金融支持的新路径，为金融助推产业集群在经济欠发达地区的率先发展，提供了重要的实践模式。

Probabilistic Bounds on the Virtual Multipliers in Data Envelopment Analysis: Polyhedral Cone Constraints

The paper is concerned with the incorporation of polyhedral cone constraints on the virtual multipliers in DEA. The incorporation of probabilistic bounds on the virtual multipliers based upon a stochastic benchmark vector is demonstrated. The suggested approach involves a stochastic (chance constrained) programming model with multipliers constrained to the cone spanned by confidence intervals for the components of the stochastic benchmark vector at varying probability levels. Consider a polyhedral assurance region based upon bounded pairwise ratios between multipliers. It is shown that in general it is never possible to identify a center-vector defined as a vector in the interior of the cone with identical angles to all extreme rays spanning the cone. Smooth cones are suggested if an asymmetric variation in the set of feasible relative prices is to be avoided.     

Regional and State Variation in Homeownership Rates; or If California's Home Prices Were as Low as Pennsylvania's Would its Ownership Rate be as High?

There are significant disparities in homeownership rates across the regions and states of the United States. The causes of these disparities are determined within a standard probit model of the individual homeownership decision where the micro-level observations are aggregated to the regional level. Factors which play a significant role at the individual level are evaluated for their ability to explain regional differentiation. The relative price of owning and renting plays a major role as do other market level determinants. Individual demographic characteristics are not as important with the exception of those related to the immigration and citizenship status of the household head.
