中国植物遗传资源(PGRs)产权配置研究——以福建武夷山国家级自然保护区为例

明确中国植物遗传资源的产权归属是落实国际生物多样性公约,实现遗传资源保护与利用的惠益分享的前提与保证。文章以武夷山自然保护区为例,结合保护区的发展特征,利用产权理论,分析了保护区植物遗传资源的保护与利用的价值形成、利益相关者及其价值需求、各利益相关者在保护和利用植物遗传资源方面的贡献与作用等,得出保护区植物遗传资源的产权配置方式。     

Concentration in ownership of plant variety rights: some implications for developing countries

This paper explores concentration levels in the ownership of intellectual property rights over plant varieties worldwide. An analysis of data for 30 UPOV member-countries shows a high degree of concentration in the ownership of plant variety rights for six major crops at the national level in the developed world. Much of this concentration has arisen owing to the rapid consolidation of the seed industry through mergers and acquisitions, especially in the 1990s. A high degree of concentration in the ownership of plant variety rights, in combination with recent efforts to strengthen plant variety protection regimes, is likely to have significant effects on the prospects for future innovation in plant breeding and the distribution of market power between companies. For developing countries, concentration in intellectual property right ownership may have important implications for the structure of domestic seed industries and access to protected varieties and associated plant breeding technologies. These implications for developing countries are likely to become apparent in the context of the rapid spread of plant variety protection and access legislation, emerging changes in the international exchange regime for plant material and liberalised investment policies permitting foreign investment in the seeds sector.

Measuring wage effects of plant size

There are large plant size–wage effects in the Nordic countries after taking into account individual and job characteristics as well as systematical sorting of the workers into various plant-sizes. The plant size–wage elasticities we obtain are, in contrast to other dimensions of the wage distribution, comparable to the plant-size effects in other countries such as the U.S. with completely different institutions of wage setting. We also investigate the consequence of measurement error associated with the common practice of using midpoints of plant-size classes to estimate the plant size–wage elasticity. Our results indicate that using size–class midpoints yields essentially the same results as using exact measures of plant size.     

The bumpy road of biomass gasification in the Netherlands: Explaining the rise and fall of an emerging innovation system

In this paper, the concept of System Functions of Innovation Systems is applied to provide an explanation of the success or failure of an emerging technology, i.e. biomass gasification, with empirical data on the evolution of this technology in the Netherlands during 1980-2004. A new list of System Functions has been developed lately and is used to identify the most relevant events in the evolution of the Biomass Gasification Innovation System. We show that a structural misalignment occurred between the institutional framework within which the technology could have been developed and the technical requirements of the technology. Finally, the absence of System Functions such as the guidance of the search, resource allocation and advocacy coalition explains the failure of this technology over time.     

The value relevance of deferred tax attributed to asset revaluations

Our study focuses on the incremental value relevance of the balance sheet relative to the income statement approach to deferred tax accounting and whether such value relevance is attributable to firms being required to report the deferred tax consequences of asset revaluations. Our results suggest that the increment to deferred tax balances upon adopting the balance sheet approach has value relevance, with such value relevance driven by the deferred taxes on certain asset revaluations (specifically, property, plant and equipment, and equity-accounted investments). We interpret our results as reflecting investors’ preference for the balance sheet approach to deferred tax accounting and their view that deferred taxes on asset revaluations are real liabilities.
