Farmland for tomorrow in densely populated areas 总被引:1,自引:0,他引:1
Valerie Vandermeulen Xavier Gellynck Guido Van Huylenbroeck Jos Van Orshoven Kirsten Bomans 《Land use policy》2009
The paper describes the results of a research that aimed to come up with a well structured method to estimate future farmland requirements in densely populated areas. By using in depth interviews, scenario analysis and strategic orientation rounds, a method is developed to support policy optimization and to explore alternative future developments. The method is applied to the case of agriculture in the Flemish part of Belgium to show the feasibility of the model and to provide input for the discussion among policy makers in Flanders. The research results can be used by policy makers to build a new Spatial Plan Flanders for the period 2007–2013. 相似文献

The univariate statistical properties of agricultural price series need to be examined as a first step in the analysis of price transmission mechanisms. However, in the case of weekly price series, increasingly available, the testing procedures usually applied in this step are not suitable to deal with evolving seasonal effects. In this study, a method of testing for seasonal unit roots in weekly series of agricultural prices is described. When the deterministic seasonal component does not remain constant over time, the restricted evolving spline model (RESM) is shown to be a useful parametric formulation to capture the deterministic seasonal pattern. Therefore, the RESM model should be included as a deterministic component in auxiliary regression for unit root tests at seasonal frequencies. This proposal is applied to three weekly series of Canary Islands banana prices. From the standard seasonal unit root tests, the null hypothesis is failed to be rejected at the 5% or 10% significance level at some seasonal frequencies for each one of the series. Once critical values are obtained by simulation exercises when the RESM model is included, the hypotheses of unit root are rejected at each one of the seasonal frequencies for all of the three series. 相似文献

Integrating the transaction cost economics and relational perspectives, this paper puts forward that technology complexity within new technology‐based firms negatively influences the level of interorganizational trust in key partner relationships. Using a data set of 105 key partner relationships of 59 new technology‐based firms, we find that the new technology‐based firm's level of trust in its key partners is lower when the level of technology complexity is high. Findings further show that both relationship and partner characteristics moderate the technology complexity—trust relationship. These results show that technology complexity as an appropriability mechanism becomes endogenous to collaboration, thereby extending the Teece framework. 相似文献

Using the lenses of institutional theory, this study examines several Entrepreneurial Factor Conditions (National Experts Survey database) while focusing on potential differences of several institutional dimensions between factor- (or production) and innovation-driven countries. This study therefore examines first the extent to which several Scott’s institutional variables (normative, regulative, and cultural-cognitive) differ according to the economic structure of countries participating in NES-GEM. Results indicate that the relevance of both regulative and cultural-cognitive dimensions differ between the group of countries driven by factor (or production) versus innovation, with a single exception, the normative dimension. Second, the study fine tunes the analysis and examines the extent to which the relevance of the aforementioned dimensions differs in two distinct institutional contexts (Portugal and Angola). Results show that the relevance of all institutional variables is different except one, the basic education and training. A possible explanation for these results may be associated to the lack of and fragility of several institutions and the absence of norms and regulations needed for a well-functioning economy, particularly in what concerns the factor (or production)-driven countries. In terms of originality, the study addresses an area of the GEM model that is under-researched. 相似文献

Recent policy from the European Union has attempted to justify social tourism initiatives on the basis that they lead to a more sustainable tourism industry. However, the majority of latest research in the field has been focused on the benefits for participants, with the addition of some evidence on the economic impacts of such programmes on destinations, which have pointed towards sustainability outcomes including: a longer tourism season, more even spread of demand, and longer periods of employment for tourism workers. Yet there is a lack of direct evidence linking such programme to these outcomes. This paper aimed to explore this important disconnect between policy assumptions and evidence-based outcomes through an analysis of the deseasonalising effects of the Spanish social tourism programme for older people. The research found that this programme does have an effect on the seasonal nature of employment and economic activity in most regions studied, but that the huge volume of demand from international tourists in the high seasons masks the quantitative effects in the regions with the highest seasonal concentration of international tourists. Recommendations for policy and practice in sustainable tourism are made that are transferable to many countries and regions that adopt social tourism programmes. 相似文献

In this article we use an autoregressive fractionally integrated moving average approach to measure the degree of fractional integration of aggregate world CO2 emissions and its five components – coal, oil, gas, cement, and gas flaring. We find that all variables are stationary and mean reverting, but exhibit long-term memory. Our results suggest that both coal and oil combustion emissions have the weakest degree of long-range dependence, while emissions from gas and gas flaring have the strongest. With evidence of long memory, we conclude that transitory policy shocks are likely to have long-lasting effects, but not permanent effects. Accordingly, permanent effects on CO2 emissions require a more permanent policy stance. In this context, if one were to rely only on testing for stationarity and non-stationarity, one would likely conclude in favour of non-stationarity, and therefore that even transitory policy shocks have permanent effects. Our fractional-integration analysis highlights that this is not the case. 相似文献

This paper shows the results of an exploratory analysis of the structure of a complex product category: Wine. In complex categories, a usual strategy of consumers is the partitioning of alternatives into homogeneous subsets and the sequential eliminations of subsets until a product/brand is chosen from among few homogeneous alternatives in the last subset. To identify if there is such a kind of strategy and the product attributes involved is of great interest for the retailer. After a discussion of the different modelling alternatives of the choice process, the authors provide an application of the additive trees (ADDTREE) model to explore the hierarchical structure. The ADDTREE results provide a first overview of the competitive market structure of the wine category: competition becomes more intense as the wine category is partitioned by, first, the type of wine criteria and, second, the designation of origin (DO) criteria. 相似文献

Consumer involvement in online shopping can play a moderating role when explaining Web site effect on satisfaction and trust. This study proposes a set of hypotheses based on the Elaboration Likelihood Model (ELM) of persuasion, a conceptual model that explains the formation of individual attitudes that are prompted by central and peripheral cues. The model proposes the use of central signals when the buyer is highly involved and peripheral signals when the buyer is less involved. Nevertheless, the results of this study would suggest that these relationships are not so clearly defined in the case of online buying, which implies that certain assumptions associated with the ELM need to be revised to take the particularities of the online context into account. © 2011 Wiley Periodicals, Inc. 相似文献

This study uses the strategic group theory to identify business strategies and competitive advantages implemented by Spanish hotels, which are grouped together according to three variables (size, chain affiliation, and category) and the degree of development of the different business strategies. An analysis carried out with the aim of checking the potential existence of significant differences in performance among the strategic groups revealed that the highest performance levels are achieved by larger-sized, chain-affiliated, and higher-category hotels as well as by establishments which base their competitive advantage on category and capacity or size and internal management. 相似文献
