Identifying and mapping the tourists⿿ perception of cultural ecosystem services: A case study from an Alpine region

Landscapes provide an array of services to society, from the provision of food and material, to the provision of cultural ecosystem services such as recreation, aesthetics or spirituality. Studies on cultural ecosystem services, however, remain rare and little is known about the spatial localisation of these services. In this study, we adopt and test a framework to identify and map the provision of cultural ecosystem services as perceived by tourists in an Alpine region, i.e. the region of South Tyrol in Italy. A photo-based questionnaire survey is combined with cartographical representations of landscape types to elicit hot and coldspot areas of cultural ecosystem service provision. We statistically test for influences of the land use type and the respondents' socio-demographic background on the tourists' perception of these services. The results show that different spatial patterns emerge for each of the investigated cultural ecosystem services depending on the distribution and extent of the landscape types to which they are related. In particular traditionally managed landscapes, small in extent and mainly scattered over large areas between 1000 and 2200 m a.s.l., are hotspot areas of aesthetic beauty, leisure activities and spirituality. In contrast, intensively managed landscapes, mainly located in the lowland plains of the study site, are considered to be more important for the provision of cultural heritage values. While the results suggest that land use type exerts the strongest influence upon tourists' perception, factors such as the respondents' perceived importance of the services, their gender, cultural background, environmental engagement and experience with the landscape play a significant but subordinate role. We conclude that the spatially explicit information about the provision of cultural ecosystem services can serve as a helpful basis for the design and further implementation of land use policies that acknowledge the high touristic value of traditionally used landscapes in mountain regions.     

Ramshackle farmhouses,useless old stables,or irreplaceable cultural heritage? Local inhabitants’ perspectives on future uses of the Walser built heritage

Social and economic developments in rural regions call for a discussion of strategies of dealing with redundant traditional buildings. Using a social science approach, our study examines how the local population in two rural regions perceives the built heritage and which factors are underlying these perceptions. People’s attitudes towards maintaining the cultural heritage vary considerably and are partly influenced by the socio-cultural and economic context of the region. The present article discusses some of the core regional socio-cultural influences on attitudes towards the rural built heritage. Following from qualitative interviews, the article concludes that the scale of perception of the built heritage is related to the “liveliness” of the local culture: The more original and distinctive the local culture is, and the more the local economy is still based on agriculture, the wider the scale of perception of the traditional cultural landscape and built heritage. In a region with local traditions that are alive and followed in everyday life, and a local economy that is mainly based on agriculture, the entire settlement structure is perceived as cultural heritage. In such areas, alternative uses should be found for redundant buildings. In contrast, in regions where the culture is less visible and alive nowadays and where the local economy has changed, people tend to perceive single buildings as representing their cultural heritage, and they often wish to preserve and conserve such remaining houses, barns and stables. In the study, we show that from a social science point of view, there is no universal perception of the maintenance of built cultural heritage. Rather, we see different views and opinions that are important to consider when it comes to developing heritage protection strategies together with public authorities.

世界遗产标准vii是UNESCO用以评价遗产地审美 价值的重要准则，由标准iii演化而来，从文化与自然美的混 合评价转向了仅对自然美学特征评价。选取以标准vii列入世 界遗产名录的145处项目(1978—2017年)，通过扎根理论 及分析，总结其运用特征、演化趋势和动因考辨。研究发现： 1)地区层面，不同地区运用标准vii所关注的审美价值具有差 异，如非洲关注色彩美学，欧洲和北美强调风景特质组合，亚 太地区重视强烈的自然文化关联、动态变化和组合关系，南美 和加勒比地区注重审美体验；2)词频运用层面，标准vii在各 地区的词频运用差异显著，各地区使用词频最高的为关于美的 “形容词”，除欧洲之外，其余地区代表“之最”特点的词频 次之；3)评价要点层面，欧洲和北美的风景特质评价具有很 强的特点与范式。最后解析了标准vii运用趋势与18世纪以来 的美学思想演变的内在联系；以期为标准vii的全球普世价值 与地区价值认知以及标准vii后续研究提供依据。     

Microdata analysis of the consequences of free trade port policy: the case of Iran free zones

ABSTRACT

Creating free trade zones as a policy to motivate new investment and improve the local economic indicators might be of some benefits. Following of this policy in Iranian major port, however, resulted vice versa by aggravating the current account balance that is higher imports and the same horizon diminished export sums. We derive the micro data of trade for the Iranian major Imam port according to code arrangements of harmonic system (HS), which permits the clustering of different goods categories. Then we extracted the sums of survey data for the years before and after Imam port became free trade zone and applied fixed effect difference in difference (DID) method to capture the heterogeneity of unobserved variables. Our control port of analysis was Rajaee port the policy did not implemented. Results show that just as Imam free port’s Current Account Balance deteriorated by increasing import and dampening of export sums.     

Official rotation and corporate innovation: Evidence from the governor rotation

Rotation is a practice whereby officials are regularly moved between equally ranked positions. Focusing on governor rotation, this paper examines the effect of official rotation on corporate innovation in China. First, we find that official rotation significantly promotes corporate innovation, including enterprises’ innovation investment, quantity, and quality. Second, we find that the effect of official rotation on corporate innovation varies because of official and regional heterogeneity. Officials rotating from other provinces significantly stimulate corporate innovation, but officials rotating from the central government have an insignificant influence on corporate innovation. In addition, officials rotating to non-eastern regions significantly enhance corporate innovation, while officials rotating to eastern regions have a negligible impact on corporate innovation. We further examine the driving mechanism behind the effect of official rotation on corporate innovation and find that officials rotating from eastern regions to non-eastern regions can significantly promote corporate innovation, but officials rotating from non-eastern regions to eastern regions do not boost corporate innovation. These findings imply that the different effects of official rotation on corporate innovation are due to the official experience effect. We also find that official rotation can promote corporate innovation through reducing corporate charitable donations and increasing corporate innovation subsidies. In a supplementary analysis, we find that GDP-oriented performance appraisal pressure weakens the effect of official rotation on corporate innovation. The lower the pressure on officials regarding their performance, the more significant the effect of official rotation on corporate innovation. In addition, official rotation can significantly promote the development of the regional economy and improve the GDP growth rate via corporate innovation, which is a micro-level economic growth effect of official rotation. Overall, our findings further verify the economic effect of official rotation and extend our understanding of the influencing factors of corporate innovation from the perspective of the official governance system. Our findings also have clear policy implications for how the government can improve the official governance model to promote corporate innovation during the transition period of the national innovation system.

Five scale challenges in Ecuadorian forest and landscape restoration governance

The forest and landscape restoration (FLR) targets set as part of the Bonn Challenge draw attention to the governance arrangements required to translate national FLR targets into local action. To achieve the targets, actors at multiple levels of the governance scale aim to influence relevant processes on the ecological scale. In this article, we focus on the scale challenges relating to the implementation of Ecuador’s restoration targets, by analysing the implementation of the 2014–2017 National Forest Restoration Plan in the montane Chocó Andino and Bosque Seco landscapes. From 54 semi-structured interviews, a document review, and geographical data analysis, we identified two temporal (i, ii) and three spatial scale challenges (iii, iv, v): i) Political cycles mismatch with FLR timelines; ii) Planning horizons mismatch with FLR timelines; iii) National restoration objectives mismatch with decentralised land use planning realities; iv) The governance level of existing FLR efforts mismatches with the level receiving restoration funds; and v) Tensions exist between the spatial dimensions of biodiversity and water-related restoration efforts. The findings highlight that more attention must be given to scale-sensitive governance to make the process in which national FLR targets are translated into local action more effective.     

金融集聚能缓解中小企业融资约束吗？——基于非线性和区域异质性的视角

以2009—2017年上市中小企业面板数据为样本，应用现金现金流敏感性模型分析了金融集聚对中小企业融资约束的影响。研究发现：整体上金融集聚可以一定程度缓解中小企业融资约束，但存在地区性差异，且门槛效应明显。金融集聚对低金融集聚水平地区的中小企业融资困境有明显改善，但其影响随着金融集聚水平的增加而减少。当金融集聚水平超过高门槛值时，这一作用非常微弱，总体上呈现非线性特征。这说明当金融资源高度集中时可能产生挤出效应。
