within a reasonable range. The output of printing and
dyeing fabric of enterprises above the scale increased
by 1.4% annually, the sales profit margin increased
from 5.2% to 5.6%, the export quantity of eight major
products of textile printing and dyeing increased by
6.8% annually, and the export value increased by
3.0% annually. 2020, the operating income of
enterprises above the scale of the textile printing and
dyeing industry was 254.13 billion yuan, and the total
profit was 12.67 billion yuan, the operating income
accounted for 5.6% of the whole textile industry.
5.6%. 2021 green laws and regulations are
implemented to make sustainable development more
important, and enterprises in the industry increase
energy saving and emission reduction.
In this paper, according to the National Economic
Classification of Industries (GB/T 4754-2017), the
main products of the printing and dyeing industry
include cotton textile and dyeing finishing (C171),
wool textile and dyeing finishing (C172), hemp textile
and dyeing finishing (C173), silk and silk textile and
dyeing finishing (C174), chemical fiber weaving and
dyeing finishing (C175). In the "2018 Input-Output
Table" the textile industry is subdivided into 8
categories, and since only two of the 8 categories in
aggregate fall within the scope defined in this paper,
the data explored in this paper are taken only from the
2 categories in aggregate for cotton, chemical fiber
textile and printing, and dyeing finishing products and
wool textile and dyeing and finishing products. The
following section will analyze the current situation of
the industry development through the input-output
method, to put forward reasonable suggestions in a
more scientific and targeted manner.

The data in this paper use the Input-Output Tables
2018 published by the National Bureau of Statistics,
in which 153 national economic sectors are published.
To be able to study the relationship between the sector
and other industries more clearly, this paper
collectively integrates 153 subdivision categories into
92 major categories according to the National
Economic Classification of Industries (GB/T 4754-
2017), according to which subsequent studies will be
more integrated output table for measurement.
