Development and application of indicator system about the quaternary industry of ecological products in China.

With the development of value realization mechanism of ecological products, the quaternary industry of ecological products supply and value realization is merging. It is expected to become a new driving force for high-quality economic development and a new mode of eco-civilization construction. Based on the classification of ecological products and the value accounting system of ecological products, this paper preliminarily formed the indicators system of the quaternary industry of ecological products in China from five dimensions including: industrial scale, industrial change, industrial structure, the extent of ecological products value realization and industrial relevance. Based on GEP accounting results, the development situation of the quaternary industry of ecological products in China was preliminary assessed and analyzed. The results showed that: ➀ In terms of industrial scale, the production of the quaternary industry of ecological products in 2019 was 92 trillion yuan, with an average five-year growth rate of 6.9%, which was basically equal to the GDP growth rate during the same time span. ➁ In terms of industrial structure, the ratio of China's ecological product supply service (EPV), regulating service (ERV) and cultural service (ECV) was 18:65:17 in 2019. Compared with the year of 2015, the proportion of primary ecological products increased by 5%, and the degree of marketization of ecological products also increased. From the perspective of ecosystem, wetland and forest ecosystems were the largest suppliers of ecological products, contributing 55% and 11% of the total output value respectively. ➂ In terms of the realization degree of ecological products value, China's average Green Gold Index was 0.96, and the primary productivity of ecological products was on the rise. ➃ In terms of industrial relevance, the degree of geographic spatial agglomeration of the quaternary industry of ecological products was increasing, and the spatial distribution was uneven. The per-capita GEP was relatively high in the western region, while the unit area of GEP in the eastern region was relatively high. However, the quaternary industry of ecological products is in the early stage of formation, and the theory and practice still need to be explored. It is suggested that we should further clarify the boundaries of the quaternary industry of ecological products, standardize the industrial classification system, improve the development index system, and integrate with the national economic accounting system, which is vital to improve the statistical investigation system of this industry, evaluating the development performance, and scientifically standardizing the collection of industrial data, so as to promote the healthy development of the quaternary industry of ecological products and the construction of ecological civilization.
