Impact of national policies on patterns of built-up development: an assessment over three decades

Globally, built-up development is taking place at unprecedented rates. To mitigate and limit its effects, recent scientific and spatial planning communities call for built-up management to be addressed on broader scales, from regional to national, and coordinated with multiple policy domains. In this paper, we aimed to analyze the evolution and impact of Romania’s national policies on built-up management during the entire period from the fall of the communist regime to the present. The new perspective offered by our study concerns the use of spatiotemporal built-up development assessment with policy analysis and visualization. Moreover, policies and built-up land changes are addressed in direct relationship with major political events and global economic influences. Our findings reveal that policies were influenced by the communist legacy, accession to the EU and the global economic crisis. Most effective were the policies adopted during the pre-EU accession period and after the economic crisis. The strongest impact on patterns of development came from policies in the domains of transportation, regional development, public administration and the environment.     

Designing business models in circular economy: A systematic literature review and research agenda

The concept of circular economy is increasingly receiving attention in different domains, including strategic management, operations management, and technology management. It requires companies to design their business model (i.e., the value network, the relationships with the supply chain partners, and the value propositions towards customers) around a new concept of sustainable development that reduces consumption of natural resources and preserves the environment. However, extant research falls short in terms of explaining how companies design their business model according to the circular economy principles. Starting from this premise, the present paper provides a systematic review of the literature on the design of business models in the context of circular economy, aiming to offer an overview of the state of research and outline a promising research agenda.

The interplay of corporate entrepreneurship,environmental orientation,and performance in clean‐tech firms—A double‐edged sword

Clean‐tech innovations are an important driver in solving global issues such as climate change and for the sustainable development of economies around the world. Whereas a large part of the literature focuses on clean‐tech ventures, less is known on corporate entrepreneurship, that is, entrepreneurial behavior in established firms and its relation to sustainability. This paper extends the sustainable entrepreneurship debate to corporate entrepreneurship, which represents a fruitful avenue to further developing clean technologies. We focus particularly on clean‐tech firms' organizational preparedness for corporate entrepreneurship (OPCE), that is, how well a firm's structures and processes are set for entrepreneurial activities. On the basis of contingency theory, this study investigates how the level of OPCE influences the environmental and financial performance of clean‐tech firms and whether their environmental orientation affects these relationships. Building on data from 103 firms, we find support for a positive effect of OPCE on both environmental and financial performance. Both effects are stronger the higher the external environmental orientation. In contrast, the leverage of internal environmental orientation is not equally positive. Our study reveals that the effect of OPCE on financial performance diminishes for firms that are more strongly driven by an internal than an external environmental orientation.     

Organizational characteristics explaining participation in sustainable business models in the sharing economy: Evidence from the fashion industry using conjoint analysis

Environmental and social challenges require new sustainable business models, like sharing platforms. However, sharing platforms differ widely in their contribution to a more sustainable society. Whereas idealistic sharing platforms have dominant social goals, other sharing platforms are, or became, commercial. We explore the attractiveness of the typical organizational characteristics of idealistic sharing platforms in the fashion industry context, an industry with negative environmental and social impacts. Based on a literature review and exploratory focus groups, we conduct an online survey using conjoint analysis, completed by 1,512 respondents. Our results reveal that potential users prefer clothes sharing platforms to be small, to not partner with large clothing retailers, to have the possibility to participate in decision‐making, but to not require shareholding.     

Depreciation of Business R&D Capital

We develop a forward-looking profit model to estimate the depreciation rates of business R&D capital. By using U.S. government data between 1987 and 2007, and the newly developed model, we estimate both constant and time-varying industry-specific R&D depreciation rates. The results comprise a set of R&D depreciation rates for major U.S. high-tech industries. They align with the main conclusions from recent studies that the rates are in general higher than the traditionally assumed 15 percent and vary across industries. The relative ranking of the constant R&D depreciation rates among industries is consistent with industry observations and the industry-specific time-varying rates are informative about the dynamics of technological change and the levels of competition across industries. Lastly, we also present a cross-country comparison of the R&D depreciation rates between the U.S. and Japan, and find that the results reflect the relative technological competitiveness in key industries.

Seasonality and regional productivity in the Spanish accommodation sector

This study quantifies the impact of peak demand and seasonality on regional productivity in the Spanish accommodation sector. We then identify factors affecting seasonal fluctuations and their relative contributions to regional variations in seasonality. The results show that demand for accommodation in the peak season mainly determines productivity. Thus, improving a region's attractiveness as a tourist destination is most effective for tourism-based regional development. In addition, reducing seasonal variations has a non-negligible impact on productivity. A decomposition analysis reveals that providing climate-independent tourist attractions and attracting business travelers are effective in reducing seasonality.     

内部控制、僵尸企业与审计特征

以2010—2017年深沪两市全部A股上市公司为研究样本，分析僵尸企业的审计特征并探讨内部控制对两者关系的调节效应。研究发现：相比于非僵尸企业，僵尸企业具有倾向于支付更低的审计费用、更有可能收到非标意见和更有可能选择非高质量审计师进行审计的特征，同时，僵尸企业内部控制环境更差。进一步研究发现，更高的内部控制质量使得僵尸企业更有可能收到标准无保留的审计意见，但非僵尸企业审计收费更高且更有可能选择高质量审计师。基于产权性质的进一步研究发现：（1）国有僵尸企业支付更低的审计费用，且中央国企支付的审计费用更低；（2）民营僵尸企业更有可能收到非标审计意见；（3）民营僵尸企业和地方国有僵尸企业更有可能选择非高质量审计师进行审计，且地方国有僵尸企业倾向性更强。从公司治理角度研究僵尸企业的审计特征，为识别僵尸企业提供了经验证据。
