ISO认证与企业创新：地理位置与组织形式的调节效应

尽管已有研究在不同情境下广泛地检验了ISO认证所引致的绩效结果,但还未充分地关注中国企业ISO认证的相关议题。利用世界银行对中国企业的调查数据,实证检验ISO认证对企业创新的影响,以及地理位置和组织形式的调节效应。结果表明,ISO认证对产品创新与过程创新均产生显著的正向影响;相较于中西部地区的企业,东部地区企业的ISO认证对产品和过程创新的正向影响更加显著;相较于合伙制与公司制的企业,独资企业的ISO认证对产品和过程创新的正向影响更加显著。     

Rental markets for cultivated land and agricultural investments in China

The purpose of this paper is to empirically track the progress and consequences of the emergence of cultivated land markets in China since 2000. We draw on a set of nationwide, household‐level panel data (for 2000 and 2008) and find that the markets for cultivated land rental have emerged robustly. According to our data, 19 of China's cultivated land was rented in farm operators in 2008. We also find that the nature of China's cultivated land rental contracts has become more formal and lengthened the period of time that the tenant is able to cultivate the rented‐in plots. While there may be benefits for lessors and tenants, our data show that there are falling rates of investment in organic manure. The farmers in our sample have reduced organic manure use from 13 tons/ha in 2000 to 5 tons/ha in 2008. Part of this fall is due to the rise of cultivated land rental markets. The analysis, however, does not find that improved property rights in cultivated land rental affect investment largely because property rights have largely been established by 2000, the first year of our sample. Our results, however, also show that there are forces that appear to be mitigating the negative consequences of rising cultivated land rental. After holding constant initial rental rates and other factors, we find that the gap between investment in organic manure in own land and rented‐in land is narrowing. One interpretation of our findings is that if policymakers can find ways to even further strengthen the rights of lessors and tenants as well as lengthen contract periods, farmers—even those that rent—will invest more in their land, because they will be able to capture the returns to their investments.     

How much trustworthy and salubrious an organic jam should be? The impact of organic logo on the Italian jam market

This paper studies the impact of organic logo in the Italian jam market. Using data on true sales in Italian supermarkets in the 2002–2004 period we estimate the structural demand model developed by Berry (1994). This approach allows us to solve potential endogeneity problem in the estimation of the price coefficient in the demand equation, as well as other aspects related to multiple sources of differentiation. In a market where 62 percent of organic jams are diet this approach allows us to identify separately the market power induced by the organic logo and by the low content of sugar. The estimation results from various specifications of GEV class of models show that the organic attribute guarantees a degree of market power greater than the diet attribute. However, the protection from competition entailed by the organic logo is not particularly strong, and the diet attribute does not guarantees additional protection to organic jams. Most importantly, our findings show that consumers trust more big organic producers thus suggesting important policy implications on the supply and marketing side of the jam market.     

What is the added value of an organic label? Proposition of a model of transfer from the perspective of ingredient branding

ABSTRACT

This paper investigates the added value of an organic ingredient strategy and the transfer mechanisms at work when placing an organic label on product brands. We proposed and empirically tested an integrated model that included three stages: brand and label equity; transfer mechanisms; and product evaluation. We first selected an organic label and product brands and then tested our hypotheses with a sample of French consumers. The results confirm the positive influence of brand and label equity on transfer mechanisms (brand/label perceived fit and ease of transfer) and, in turn, illustrate how ease of transfer influences the overall product evaluation. A surprising result is that brand/label perceived fit does not directly affect the overall product evaluation; rather, it only influences brand/label ease of transfer.

The Europeanization of organic agriculture and conflicts over agricultural policy

Organic agriculture was Europeanized through two EU regulations which defined and provided financial support for it. In transposing these regulations, member states have had to deal with political aspects of the conflict between mainstream and organic agriculture. A comparison of 13 new (including former socialist states) and old member states illustrates that the level of conflict had an impact only on the level of financial support transposed, while other aspects of transposition were explained by formal institutional preconditions. Low financial support was found in those member states with a high level of conflict or a low value-based level of conflict. Medium financial support was found in one new and one old member state characterized by medium level conflicts. High financial support appeared in three member states characterized by truly low level conflicts in terms of common organic and mainstream agriculture interests.

Scenarios of the organic food market in Europe

Scenario analysis is a qualitative tool for strategic policy analysis that enables researchers and policymakers to support decision making, and a systemic analysis of the main determinants of a business or sector. In this study, a scenario analysis is developed regarding the future development of the market of organic food products in Europe. The scenario follows a participatory approach, exploiting potential interactions among the relevant driving forces, as selected by experts. Network analysis is used to identify the roles of driving forces in the different scenarios, and the results are discussed in comparison with the main findings from existing scenarios on the future development of the organic sector.
