n this paper, a model to evaluate the change of prices of
green products by sector compared with their traditional
prices in 2 waste treatment management modes is
established. The criterion is provided for the choice of the
waste treatment management mode; this is accomplished
by considering waste treatment costs as well as making full
use of each product’s price advantage all within the context
of the macroeconomic system. The model is applied in
wastewater treatment case in China. The changes in prices
for 42 sectors in 4 scenarios are evaluated. The results reveal
that the price for each sector’s green product increases
compared with that of its more traditional product. At the
sector level, the price increases for Oil and gas extraction
products, Metal products, machinery and equipment repair
services, Petroleum, coking products and nuclear fuel
processing products ranked in the top 3 in scenario 1. In the
other scenarios, their ranks are different. The results further
show that the price increases of 22 sectors are mainly caused
by other sectors’ added waste water treatment costs. The
change of prices for green agricultural products would have
a significant impact on their demands, in some cases, causing
their annual demands to decrease. From the perspective
of price advantage, the producers and administrative
organizations are encouraged to consider the combination
of two waste treatment management modes for 42 sectors.
To limit the waste water discharged in China, one possible
intervention would be to increase the fine imposed for unit
waste water discharged, setting it at a higher level than
the unit waste water discharge fee and its treatment cost.
Furthermore, it is suggested that the waste water treatment
cost needs to be reasonably incorporated in the products’
prices, a suggestion that can be adopted in the model used
in this paper.
