我国资本市场存在的制度功能缺陷与对策

我国资本市场是在新旧体制转换中建立起来的，先天就存在着制度和市场功能方面的缺陷，亟需要采取有效应对策略以弥补，使我国资本市场的发展走上正常轨道。     

论股东表决权的限制

表决权是股东最本质的固有权利,原则上不得剥夺并限制。但是,决议的最终目的是公正地产生股东们普遍意愿,决议应代表全体股东或大多数股东的利益。但有时候会存在大股东滥用表决权或表决权的行使会损害公正性的危险。因此,本文将从股东表决权的限制角度,阐述如何实现对中小股东利益的保护。     

Optimization of Harvesting Return from Age-Structured Population

Synopsis Maximization of the net profit from harvesting in a one-species age-structured population is analyzed. One of the control functions is the age of harvested individuals. The constructed mathematical model is similar to vintage capital models used in economics for optimal capital replacement. The optimization technique developed by authors for the capital replacement is disseminated to the formulated problem. A qualitative analysis of the problem is provided and the interpretation of results is given. Such economic topics as a zero-investment period, optimal balanced growth, and turnpike properties are discussed.     

中华民族的伟大复兴，呼唤马克思主义及其经济学的指导

中国的经济快速增长，正在和平崛起，但中国目前仍是一个发展中国家，人均GDP较低。中华民族需要复兴，但这需要马克思主义及其经济学的指导。西方经济学有其不可克服的阶级局限性，它维护私有制而反对公有制，承认差别而不主张共同富裕，主张自由竞争而反对政府调控，维护发达国家利益而无视发展中国家利益，更无解决“三农”问题之策，等等。所以，我们必须坚持特别是要发展马克思主义及其经济学，当然还需注意吸收西方经济学的可取之处。公有制与市场经济的结合、公平与效率的协调、市场调节与宏观调控的关系、城乡关系、地区关系、政企关系、官民关系等一系列重大问题，都需要马克思主义及其经济学进一步作出科学回答。

我国人民代表大会行使预算监督权的制度缺陷分析

各级人大的预算监督是预算监督体系中最为重要的一环,但多年以来由于诸多原因,人大的预算监督职能被严重弱化,其在预算监督体系中的主体地位无法体现,甚至有让位于其他监督形式的趋势,这不能不引起我们的重视。本文着重分析了阻碍人大充分发挥其职能的种种制度缺陷,以期对相关法律制度的健全有所帮助。     

建设项目设计阶段的投资控制

针对近年来国内建设项目普遍存在“三超”现象，分析了造成严重投资失控问题的主要原因，指出在设计阶段进行投资控制对于全面控制建设项目总投资的重要性。研究了如何运用价值工程、推行优化设计、限额设计和标准设计等方法，达到在设计阶段有效地控制投资的目的。     

浅谈工程项目投资的全过程控制

章简述了工程项目投资全过程控制的原理，以及各阶段对工程项目投资控制所起的作用和控制的方法。在工程建设中投资控制应注意抓住投资决策控制和设计控制，它们是工程项目投资的全过程控制的关键性环节。     

Optimal harvesting of a spatial renewable resource

In this paper we investigate the optimal harvesting of a renewable natural resource. While in most standard approaches the resource is located at a single point, we allow the resource to be distributed spatially. Consequently, an agent who exploits the resource has to travel from one location to another. For a fixed planning horizon, we investigate the speed and the path of harvesting chosen by the agent. We show that the agent adjusts this speed so as to visit each location only once, even in the absence of travelling cost. Since the agent does not return to any location for a second harvest, it is optimal to fully deplete the resource upon arrival. A similar type of bang–bang solution results when we drop the assumption of a constant harvesting rate: allowing for a variable harvesting rate, the agent chooses to fully exploit the resource either in the last or in the first travelling period. A society interested in conserving some of the resource thus has to take measures to limit the exploitative behaviour of the agent.     

An adaptive approach to forecasting three key macroeconomic variables for transitional China

The macroeconomic forecasts for emerging economies often suffer from the constraints of instability and limited data. In light of these constraints, we propose the use of a local autoregressive (LAR) model with a data-driven estimation window, i.e., a local homogenous interval, that is adaptively identified to strike a balance between information efficiency and stability. When applied to three key macroeconomic variables of China, the LAR model substantially outperforms the alternative models for various forecast horizons of 3 to 12 months, with forecast error reductions of between 4% and 64% for the IP growth, and between 1% and 68% for the inflation rate. The one-quarter ahead performance of the LAR model matches that of a well-known survey forecast. The patterns of the identified local intervals also coincide with the characteristic evolution of the gradual reforms and monetary policy shifts in China. In short, the LAR model is suitable for not only forecasting, but also the real-time monitoring of the effects of regime and policy changes in emerging economies.
