Q58 - Environmental Economics: Government PolicyReturn

Fertilizer has brought great pressure to sustainable ecological environment. Research on the effect of price on fertilizer use as well as the substitution relationship of fertilizer and other input factors of agricultural production is of great importance for green, efficient, and intensive agricultural production in the world. This study first constructs translog cost functions and models of elasticity, then uses the factor input and price data from 2004 to 2016 to measure the price elasticity of fertilizer demand, and the elasticity of factor substitution in China's maize and cabbage production. The results suggest that: the price elasticity of fertilizer demand is in a low elasticity range; there is a compensation relationship between fertilizer and labour and a substitution relationship between fertilizer and machinery in China's maize production, while these relationships in China's cabbage production are opposite.

The purpose of the survey and to some extent polemical article is to present the issue of green growth, a new operating strategy, which the OECD is currently working on. Green growth is seen as a practical tool for achieving the timeless objective, which is sustainable development. In the paper, a particular attention is put on the following question: what kind of relationship occurs between green growth, green economy and sustainable development. The author analyses the purpose of simultaneous functioning of the three "green" ideas. The added value of this paper is a presentation of the author's model of GG-GE-SD relations and a new approach to defining the phenomenon of green growth. It is concluded that co-existence of the trio green economy - green growth - sustainable development is reasonable due to the complementary and synergistic nature of correlations between these concepts.

Environmental information disclosure instruments inevitably also carry information costs. It is important to pay attention to these costs because of the competitiveness issues connected with the regulatory burden of the private sector or the overall cost-effectiveness of different types of environmental regulation from the public sector point of view. We undertake an ex-post analysis to quantify and analyse reporting costs of private sector induced by the European Pollutant Release and Transfer Register (E-PRTR). We focus on the case of the Czech Republic. The average annual reporting costs, additional to other reporting duties, are € 365 per facility. The Czech PRTR comprises 8 times more facilities than required by the European law, and thereby increases correspondingly the total reporting costs. The best predictor variable of the costs is the need for measuring or calculating additional releases or transfers beyond the information requirements of other registers.
