Technological progress and Chinese agricultural growth in the 1990s

The paper examines the factors contributing to the sharp recovery of China's agricultural production in the 1990s in contrast to the stagnation in the late 1980s, and analyzes the policy effects during this period paying special attention to the role of technological progress. Using data from 28 provinces covering the years 1991–1999, a conventional production model and an extended production model with time-effects are estimated using random-effects estimation and a growth accounting for land productivity is evaluated. The results show that technological progress plays the dominant role in the recovery, accounting for 58% of total productivity growth during the sample period, while an increase in fertilizer use is second, with about 19%. Extension of the land tenure to 30 years for farm households could be a policy encouraging adoption of new technologies and more investment. The contribution of this policy change accounts for 21% in the productivity growth in the period. Increase in mechanized farming, plastic film input and education are all factors contributing to China's agricultural growth in the 1990s.     

金融腐败与被监管者自我报告制度研究

金融腐败与金融监管有着重要联系,而且在金融监管及惩处的执法过程中会存在着监管腐败问题。文章在金融监管执法活动中构建了一个具有腐败倾向特征的监管执法者对金融机构或其从业人员的违法行为监督执法的模型,指出一个福利最大化的政府可以通过实施适当的激励政策以防范监管者和被监管者之间合谋腐败的发生,同时证明了如果允许金融活动参与者在违法行为发生后可以实施具有恰当的惩罚激励措施的自我报告制度,政府就能够通过降低官僚作风、保持较少的监督执法官员、降低监管寻租以增加社会福利,并通过自我报告制度消除金融腐败而进一步为社会谋福祉。     

发达国家城市拥堵治理经验对武汉市的启示

伴随迅速推进的城市化进程,不断扩大的城市规模,交通拥堵问题已演变成为一种常见的"城市病"。发达国家最早进入机动车高速发展阶段,在城市交通拥堵问题上经历较早,研究也较多。由于影响城市交通的因素很多,从不同角度分析就会产生不同的交通拥堵治理模式。概括说来,国外发达国家交通拥堵治理主要从引导需求、增加供给和加强管理等3个方面进行。     

Labour Markets in China: A Study of the Structure and Evolution of Wages

This paper examines the development of labour markets and the evolution of a structure of wages in China, using household surveys for 1988, 1995, 2002 and 2007. It finds evidence of both provincial and sectoral segmentation in labour markets, with eastern regions and the state-controlled sector enjoying high wage premiums in the early reform period. During the reform, China has progressed slowly towards an integrated labour market with convergence in incomes between the rural non-agriculture sector and the urban market-based sector by 1995, when industry flourished in the rural areas. The wage gap between the rural non-agriculture sector and other sectors increased and the urban state-controlled sector remained segmented with respect to all other sectors up to 2002. However, the data from 2007 show there has been increasing sectoral and spatial integration.     

老龄化、服务性消费与第三产业发展--来自中国省级面板数据的证据

本文基于2003－2013年的中国省级面板数据,通过引入老龄化与服务性消费比重的交互项,综合运用多种静态和动态面板数据模型和稳健性分析,考察老龄化通过服务性消费渠道对第三产业发展的影响。研究结果表明,老龄化对第三产业发展具有负向影响,但老龄化引致的服务性消费比重的提高能显著减弱这一负向影响。进一步扩展讨论的结果证实,服务性消费确为老龄化影响第三产业发展的重要渠道,提高民生性财政支出、保障公共服务均等化及提升金融发展水平有利于释放老年人口的服务性消费需求,拉动第三产业发展。

Multinationals,Information Update,and Product Adaptation *

This paper develops a dynamic model of decision making by multinational firms. The firm chooses between exporting and producing abroad when it expands the market. Bayes learning is incorporated into this model in addition to fixed cost and transport cost Production in a foreign country gives the firm new information about the demand function. This information is applied to adjust the firm's expectation as well as output choice in the future. This process not only reduces the risk encountered by a firm in a foreign market, but also increases acceptance of the product which the firm manufactures. This paper concludes even if producing abroad loses money in the first period, the firm may still choose to set up plants in foreign countries rather than exporting, due to the dynamic information advantage associated with going multinational.

香港“轨道交通＋土地综合利用”模式的启示

香港＂轨道交通＋土地综合利用＂的模式是一种集地铁投资、建设、运营和沿线土地综合开发于一体的综合开发模式,是由港铁统筹开发的。从运作流程上分为项目谋划、项目明确、项目开发和项目运营四个阶段,在营造高效率的公共交通体系、促进土地高度集约、节约利用等方面都取得了明显效益。对我国城镇交通发展有五点启示和借鉴：（1）交通规划与土地规划同步进行、有机结合;（2）推进经营性土地有偿使用;（3）运用节地技术和模式,充分发挥土地的复合利用功能;（4）分层出让,实现土地利用的多元化价值;（5）拓展融资渠道,实现轨道交通多渠道投融资。
