知识产权与网络经济

产权是一个社会的基本经济规则，它从根本上决定经济的组织和效率。知识产权是现代经济增长的基本因素，与企业制度的安排从而与市场效率有关。对现代经济来讲，知识产权最重要的实现形式是企业制度的安排，同时企业制度也是重要的保护知识产权的方式，法律上的保护更多的是事后救济。

Intelligent agents for adaptive security market surveillance

Market surveillance systems have increasingly gained in usage for monitoring trading activities in stock markets to maintain market integrity. Existing systems primarily focus on the numerical analysis of market activity data and generally ignore textual information. To fulfil the requirements of information-based surveillance, a multi-agent-based architecture that uses agent intercommunication and incremental learning mechanisms is proposed to provide a flexible and adaptive inspection process. A prototype system is implemented using the techniques of text mining and rule-based reasoning, among others. Based on experiments in the scalping surveillance scenario, the system can identify target information evidence up to 87.50% of the time and automatically identify 70.59% of cases depending on the constraints on the available information sources. The results of this study indicate that the proposed information surveillance system is effective. This study thus contributes to the market surveillance literature and has significant practical implications.     

The response of U.S. natural gas futures and spot prices to storage change surprises: Fundamental information and the effect of escalating physical gas production

We study the behavior of U.S. natural gas futures and spot prices on and around the weekly announcements by the U.S. Energy Information Administration of the amount of natural gas in storage. We identify an inverse empirical relation between changes in futures prices and surprises in the change in natural gas in storage and that this relation is not driven by the absolute size of the surprise. The evidence also indicates prices react first in the futures market for natural gas with that information then flowing to the spot market. Post 2005, corresponding to a period of significant increases in the production of natural gas in the United States, the response of prices to storage surprises was larger in absolute value. No evidence is found of economically meaningful reactions to the surprise other than on the date the storage news is released. The results demonstrate the importance of fundamental information in the formation of natural gas prices.     

Implications of domestic price insulation for global food price behavior

Rapid changes in global food prices in recent years are widely viewed as a serious threat to global development. While various sources of price instability in agriculture have been identified, little attention appears to have been given to the importance of changes in trade policies that insulate domestic prices from world markets as a source of volatility in world prices. A contribution of this paper is to show that these interventions are dynamically more complex than simple proportional insulation. Insulation against an initial price increase in world prices increases the magnitude of that increase, while subsequent adjustments to the level of protection change the fundamental nature of price volatility. We find such policies are widespread and increase the volatility of world prices while not reducing the volatility of domestic prices because of the collective action problem involved in this form of policy intervention.     

智能通行证管理平台构建

随着经济的快速发展和汽车保有量的迅速增长,各类单位基于安全性的管理,可能每辆汽车都配有很多不同地点的通行证,如何放置和管理这些通行证,并制订更加合理有效的管理策略是本论文所要解决的问题.针对通行证的授权管理及显示所遇到的问题,本论文基于GPS技术、信息技术、液晶屏显示技术提出了一种新的智能通行证管理平台的构建,为解决各类通行证授权及其显示方式提出新的方案.     

国外实施技术性贸易壁垒的新动向及我国的应对措施

技术性贸易壁垒(TBT)作为一种无形的非关税壁垒,正日益成为国际贸易中最棘手、最难应付的贸易障碍之一,并正在对我国的出口贸易产生显著的影响。而技术标准作为发达国家实施TBT的重要手段之一,已成为当今国际经济竞争的制高点。技术标准不仅是保护国内市场的标志,而且是争夺国外市场、提高国家竞争力的有力手段,是国家利益和价值观念的载体。近年来,发达国家为了保护自身利益、限制他国发展,纷纷制定和实施标准化战略。本文首先分析了现阶段美国、日本和欧盟的主要技术标准壁垒及其标准化战略的新动向,在此基础上,从宏观和微观两个层面提出了我国应对国外技术标准壁垒的战略措施。
