In this article, we scrutinize the innovation trajectory of eco-cement in the Netherlands by examining the innovation nexus of eco-cement manufacturers, scientists/researchers, waste producers and policymakers as part of a broader analysis of markets, policy and society, with special attention to standards and regulations. The influence of policy and innovation interactions are substantiated by policy documents, media news, patterns of eco-cement use, and in-depth interviews conducted with relevant eco-cement actors. Our analysis brings forward empirical evidence of how policymakers are involved in the innovation trajectory of eco-cement in multiple ways through building regulations, sector policies, waste policies, and science and innovation policies. Political economy aspects of regulation and innovation in cement industry (e.g. the cooperative approach of waste authorities with regard to re-use of waste, absence of policies to put a price on CO2 emissions from cement production) are being described, together with the specificities of the cement market. Bans on the disposal of fly ash and sewage sludge resulted in the use of those materials either as a supplementary cementitious material or a fuel. Demand for green cement from is presently growing but meets with several obstacles. Carbon policies are shown to constitute a weak influence. Innovation in eco-cement co-evolved with policy, through mutual dependencies, as a theoretical finding for innovation studies.  相似文献

This article considers a transition toward European monetary union that combines increased substitution of currencies and greater monetary, financial, and fiscal policy coordination. It explores how such a transition would affect national inflation and interest rates and required reserve ratios when governments depend in part on seigniorage funding for public expenditures. We find that greater coordination of policies would lead to lower inflation and interest rates but higher reserve-requirement ratios. Because higher reserve-requirement ratios could place European banks at a competititve disadvantage, we conclude that the interaction between reserve requirements and seigniorage concerns makes it less likely that the gradualist approach of the Maastricht treaty is a sustainable means of transition to European union.  相似文献

For many countries, export-driven policies have thus far produced dramatic increases in real per capita income. At the same time, sustainable growth requires that technological innovation proceed at comparable rates if mutual gains from globalization are to be realized. In this paper, we derive a measure of innovation and test the extent to which institutional policy choices enhance or delay its diffusion. To do so we use a panel regression model, with data on a sample of 103 countries in different geographic regions for the 1980–2005 period. Our findings provide empirical evidence of the positive role of creative innovation in economic growth, and from which we derive several basic policy conclusions.  相似文献

ABSTRACT

Rising calls on sustainable practices ignited the need for hotels to develop innovative and sustainable ideas and approached to conserve the environment. This paper examines and discusses the existence and application of innovative sustainable environmental practices within Malawi hotels. Qualitative approaches were adopted to collect the data from public and private actors in the accommodation sub-sector. The Rogers Diffusion of Innovation Theory was used to determine the most prevalent reason for adopting an innovation strategy within some of the hotels in Lilongwe. It is reviewed that to a lesser extent some hotels adopted innovative strategies in water and energy use, waste management and hotel design. The collaborative effort between the government and private sector and the strengthening of the implementation of sustainability policies is recommended to promote environmental sustainability innovation. These views have been discussed within the broader discourse on environmental sustainability and innovations within hotels, in the Sub – Saharan African context.  相似文献

This article focuses on the prospects of the financial systems approach to development finance to ensure sustainable access to financial services for microentrepreneurs. It discusses three prerequisites for the success of this approach: the continued application of financial liberalisation policies; the delivery of financial services on a commercially viable basis by emulating the successes of informal financial intermediaries in solving the problems normally experienced by the formal financial sector when serving microentrepreneurs; and the continued appropriate support from governments and the donor community. It is postulated that these prerequisites will be fulfilled, making the author cautiously optimistic that the financial systems approach to development finance will succeed in securing sustainable access to financial services for microentrepreneurs in the 21st century.  相似文献

The continuously accelerating global energy demand leads to increased public concern about climate change. The international community expects China, the world's largest energy consumer, to play a leading role in the energy transition, especially since the United States has withdrawn from the Paris Agreement. This special issue on “Energy Demand in Emerging and Developing Economies: Measurement, Policy Interventions and Evaluation” improves international understanding of the patterns of energy demand in China by presenting recent experimental and empirical research following the Beijing Energy Conference in 2018. The main purpose of this introductory article is to present recent research advances by summarizing new findings and insights from this special issue, combined with recent literature. It shows that China's rising energy demand and energy transition practices have led to numerous policy interventions, which provides rich observational data on behavioral change and offers an “experimental window” with large opportunities for scholars. Beyond the traditional topics of residential and industrial energy demand and its drivers, an increasing number of studies focuses on energy policy evaluation or quantify the environmental and climate consequences of energy consumption. This new line of research, supported by policy-oriented model-based quantitative analyses, experimental approaches and econometric analyses using multi-source disaggregated data, offers new insights into various aspects of China's energy demand.  相似文献

Lead markets, innovation differentials and growth   总被引:1,自引:0,他引:1  
This article suggests that the specialization of countries in international trade is determined by the lead-lag market pattern of national markets. Many internationally successful innovations have been adopted first in one country while other countries initially either preferred other designs or an established product. A model for the international diffusion of innovations is presented in which nationally preferred innovation designs compete to become a globally dominant design. In this model, there are country-specific market attributes that increase the likelihood that the choice a country makes among alternative technologies is followed around the world. It is argued that technological knowledge gaps are not the origin of an international competitive advantage. Instead, a country gains a competitive advantage because a specific innovation design was adopted earlier than in any other country. This gives local firms a head start in producing, gathering marketing intelligence and securing the property rights of a globally successful innovation. In countries with lag market characteristics, domestic innovations are less likely to get adopted worldwide. Lag markets often switch from a domestic innovation design to a foreign innovation design, which increases imports. The lead-lag market explanation of trade specialization has implications for national policies. In this model domestic innovations do not always foster exports; idiosyncratic innovations induced by lag market contexts can hamper the export chances of local firms and in the end lead to an increase in imports. It is suggested that in order to increase exports, national policies have to distinguish between a domestic lead and lag market context in each industry. While in a lead market context, traditional policy instruments that enhance the rate of innovations are effective, in a lag market situation national follower strategies are more appropriate.  相似文献

Multinational firms are increasingly sending their innovative tasks abroad. This article examines whether offshoring research and development, design, and engineering activities provides any gains in terms of firm‐level innovation output. The effects of trade in innovative tasks on the probability of firms being innovative and the share of innovative product sales in total turnover are examined using an instrumental variable approach. The data in use come from a recent survey, which provides cross‐section observations for more than 14,750 firms in seven European countries. The results suggest that those firms that offshore their innovative activities are 60% more likely to successfully innovate. Also, offshoring innovative activities increases the share of innovative product sales in total turnover up to 35%. Furthermore, firms in this sample appear to gain from trade in innovative tasks when such trade is in product innovation but not when such trade is in process innovation.  相似文献

In the wake of economic development and raised living standards, Chinese pork consumption has risen significantly. As a response to the increased demand and active government support, the national hog sector, which was traditionally dominated by small backyard farms, is featuring a quick restructuring towards large-scale breeding enterprises. With the transformation of the hog sector, environmental externalities have become a very serious concern. Foremost non-point source pollution resulting from the leakage of pig waste into surface water and groundwater resources is seen as a serious threat. Via data envelopment analysis (DEA), we approach the question of efficiency gains from both technical and environmental perspective along a 2012 sample of 371 Chinese hog farms. Our results suggest that especially mid-size hog farms in transition face low environmental efficiency and high pollution abatement costs due to limited waste disposal options. Existent policies turn out to be yet hardly effective in decreasing environmental externalities. In some provinces, projects for rural biogas production could help to improve waste management. However, especially small farms require state support towards improving storage and transportations facilities.  相似文献

The objective of the Macroeconomic Reforms and Sustainable Development in Southern Africa project was to facilitate the attainment of sustainable development objectives agreed at the United Nations' Earth Summit held in Rio de Janeiro, Brazil, in June 1992, in which Tanzania participated. The two natural resource-based sectors of tourism and mining were chosen for analysis. Despite the difficulty of linking policy explicitly to particular economic activity performance, macroeconomic indicators show that economic policies stimulated economic activity resulting in, among other things, a significant increase in economic growth, declining inflation, declining deficits, and an increase in tax revenue collection. The mining and tourism sectors' share of GDP increased significantly, and both sectors have contributed greatly to employment generation. However, these economic gains have come at the cost of environmental degradation, social hardship and the breakdown of social norms and values. Such results indicate that the country is not yet on a sustainable development path. While good policies exist and are being improved, there has been a failure of policy implementation over the years. With good policies, appropriate integrative strategies, commitment and political will, the country may attain a sustainable development path.  相似文献

This article analyzes endogenous efficiency gains from mergers. It considers oligopolistic homogeneous good markets and duopolistic and triopolistic markets under product differentiation (PD) (quantity and price competition). In a two‐stage game, firms invest in cost‐reducing innovation (with and without mergers) and then compete in output/prices. It is found that in homogeneous good markets, all possible mergers generate efficiency gains, and that these are most significant when R&D spillovers are very low or very high. Efficiency gains increase with the number of insiders and generally decrease with the number of outsiders. With PD, in most cases, the merger generates efficiency gains when spillovers and/or PD are sufficiently high. With PD, efficiency gains increase with spillovers, but may increase or decrease with the level of PD. The implications of the results for the relationship between competition and innovation outputs and for merger policy are discussed.  相似文献
