改革开放30年我国农村建设成就——一个综合评价模型及其应用

首先,对改革开放30年来农村建设的实践进行了阐述。接着,运用层次分析法建立了综合评价模型,并对农村建设进行了实证分析。最后得出,改革开放之后,农村建设取得了巨大的成就。这个时期的农村建设大致可以分为两个阶段,在第一个阶段农村建设主要是由于农业发展和农村和谐建设带动的,而在第二个阶段农村建设则主要是由于农民素质提高拉动的。     

Was there policy “reform”? Evolution of EU domestic support for processed fruits and vegetables

Policy “reform” in agricultural markets is often associated with less government regulation and expenditures, or a shift towards more efficient interventions. The European Union (EU) adopted major policy changes for processed fruits and vegetables in 2001 and again in 2008, and we employ a simulation model to examine the effects of the three policy regimes in place before and after each of the changes. Our analysis incorporates the heterogeneity of processing firms in the EU and considers how they responded to the different policy regimes. Simulation results indicate that the EU subsidies increased EU tomato production by 3.8% for the regime that began in 2008 and 9.1% for the regime that began in 2001 compared to no subsidies. The policy regime that was in place from 2001 through 2007 led to the greatest distortions in global processing tomato markets, in part because it directed more of the benefits to EU growers and less to EU processors and consumers. Thus changes in 2001 “reformed” policy by redistributing gains within the EU, while changes in 2008 “reformed” policy by reducing distortions in global markets.

Learning from processing trade: Firm evidence from China

Processing export plays a significant role in international trade. In this paper, focusing on firm-level dynamics, we show that firms learn from their processing export experience to improve their subsequent ordinary export outcomes. Using transaction-level trade data and firm-level production data, we show that firms’ ordinary export performance, at both extensive and intensive margins, is enhanced by their own processing experience. Firms also export products with improved quality after engaging in processing exports of similar products. Furthermore, we investigate potential channels through which firms learn from processing experience. We find that firms potentially learn from processing experience to enhance production efficiency, to better understand how to improve product appeal to cater to specific markets, and to gain better and easier access to inputs. Moreover, we find that exporters benefit more from processing experience for larger markets with fiercer competition. Similarly, stronger learning effects are also observed when processing experience is associated with products that embody less diffused knowledge and are more differentiated. Also, firms learn more from processing experience when they are more actively engaged in processing imports. Lastly, we verify the economic significance and quantify the importance of these potential channels.     

加工贸易视角下中美工业贸易隐含碳研究：国别排放与全球效应

本文基于加工贸易视角,区分国内与进口中间投入,构建贸易隐含碳模型,从工业整体及行业角度分析了1998—2009年度中关工业贸易隐含碳的国别排放情况,并基于全球视角分析了中关贸易的全球净效应。结果显示：中国对美工业贸易始终处于隐含碳净出口状态,2001年之后（净）出口隐含碳增幅尤其明显,其中化学、机械、纺织业是隐含碳净出...

试论我国出口市场多元化战略实施

出口市场多元化应包括四个方面的内涵:首先,市场多元化是指区域多元化,即出口市场应全方位、多角度分布于世界各地,而不仅仅聚集于少数市场;其次是指商品多元化,因为商品是市场的核心内容,一国对外贸易,不单单是点多、面广,而且商品品种、规格、档次等都要多样化,才能符合不同消费层次的需求;第三,出口市场多元化应包括经营手段的多样化,即开拓海外市场要采取灵活多变的方式、方法。     

Information processing and innovative choice

In this paper we examine how the information processing of subjects who make an innovative choice (innovators) differs from that of subjects who make a noninnovative choice (noninnovators). The task involves selection of an alternative within a range of prerated product category innovativeness. We propose that subjects who seek 1) impersonal/uncontrollable sources, 2) higher levels of information, 3) more detailed (versus summary) data, and 4) noncomparative (versus comparative) data are more likely to make innovative choices. The research method is a computerized process tracing experiment utilizing Search Monitor (Brucks 1988).The authors wish to express their gratitude to Merrie Brucks for the use of and help with Search Monitor and to Eric Johnson, Dave Schmittlein, and Mita Sujan for helpful comments on an earlier version of this paper.
