Investigating the environmental Kuznets curve between economic growth and chemical fertilizer surpluses in China: a provincial panel cointegration approach
(2022) Yu, Xiaomin; Schweikert, Karsten; Doluschitz, Reiner
This study investigated the relationship between fertilizer nitrogen (N) and phosphate (P) surpluses and economic development on the regional level in China. With a balanced panel dataset covering 30 provinces of mainland China from 1988 to 2019, we employed panel cointegrating polynomial regression (CPR) analysis using fully modified OLS (FM-OLS) estimators. Our results suggested that all provinces exhibit a long-run cointegrated relationship between fertilizer surpluses and real per capita gross regional product (GRP). A total of 22 provinces out of 30 showed a significant inverted U-shaped environmental Kuznets curve (EKC). Among those, 14 provinces are considered to have reached the peak and 8 provinces are considered to be before the peak. The group-mean turning points on the EKC are CNY 7022, CNY 9726, CNY 4697, CNY 3749, and CNY 5588 per capita GRP (1978 = 100) for the Northeast, Northcentral, Middle, and lower reaches of the Yangtze River, Southwest and Northwest China, respectively. The overall turning point of China is CNY 6705 per capita real gross domestic product (GDP), which was reached in circa 2012. This shows a general improvement of chemical fertilizer management in China. However, six provinces still exhibit linear growth in fertilizer surpluses when the economy grows. These regions are characterized by high cash-crop ratios and are mostly located along the southeast coast. Therefore, more effort and attention should be given to these regions to promote further fertilizer reduction. At the same time, nutrient use efficiencies should be improved, especially for cash crops such as fruit and vegetables.
Quo vadis, bioeconomy? the necessity of normative considerations in the transition
(2021) Urmetzer, Sophie; Schlaile, Michael P.; Blok, Vincent; Pyka, Andreas
This collection of papers builds on the idea that the bioeconomy provides a framework for potentially effective solutions addressing the grand global challenges by a turn towards an increased use of biological resources, towards renewability and circularity. Consequently, it cannot be perceived as an end in itself. Thus, innovative endeavors within this bioeconomy framework require a serious examination of their normative premises and implications. From different perspectives, the five contributions to the collection demonstrate that for a bioeconomy that is to contribute to the transformation towards sustainability, inquiries into norms, values, and paradigms of innovators and other stakeholders are indispensable. Originating in the spirit of an interdisciplinary workshop on the “The Normative Dimension of Transformations towards a Sustainable Bioeconomy”, the collection at hand provides an attempt to facilitate an increased commitment of social sciences into bioeconomy discourses. We learn: the bioeconomy is on the rise as it is, but whether it will guide us the way towards an equitable, environmentally sound, and future-proof economy, heavily depends on the normative guardrails imposed by science, society, and business.
Time to say ‘good buy’ to the passive consumer? A conceptual review of the consumer in the bioeconomy
(2021) Wilke, Ulrich; Schlaile, Michael P.; Urmetzer, Sophie; Mueller, Matthias; Bogner, Kristina; Pyka, Andreas
Successful transitions to a sustainable bioeconomy require novel technologies, processes, and practices as well as a general agreement about the overarching normative direction of innovation. Both requirements necessarily involve collective action by those individuals who purchase, use, and co-produce novelties: the consumers. Based on theoretical considerations borrowed from evolutionary innovation economics and consumer social responsibility, we explore to what extent consumers’ scope of action is addressed in the scientific bioeconomy literature. We do so by systematically reviewing bioeconomy-related publications according to (i) the extent to which consumers are regarded as passive vs. active, and (ii) different domains of consumer responsibility (depending on their power to influence economic processes). We find all aspects of active consumption considered to varying degrees but observe little interconnection between domains. In sum, our paper contributes to the bioeconomy literature by developing a novel coding scheme that allows us to pinpoint different aspects of consumer activity, which have been considered in a rather isolated and undifferentiated manner. Combined with our theoretical considerations, the results of our review reveal a central research gap which should be taken up in future empirical and conceptual bioeconomy research. The system-spanning nature of a sustainable bioeconomy demands an equally holistic exploration of the consumers’ prospective and shared responsibility for contributing to its coming of age, ranging from the procurement of information on bio-based products and services to their disposal.
