Keywords: Small Giant Enterprise, Little Giant Enterprise, Jiangsu Province, Gray GM (1.1) Model, Patent Number.
Abstract: The number of patents is an important index to measure the technological innovation ability of an enterprise.
If the most accurate as possible predictions can be made about the number of corporate patents in the region,
It has a positive significance for the future economic development and policy formulation of the region, This
paper uses the gray GM (1.1) model to predict the patent number of listed companies in the "specialization,
refinement, characteristics and novelty" Little giant enterprises in Jiangsu Province, Using the 7-year data
from 2013-2020 as raw data for grey predictions, Establish the prediction model of patent number of
"Specialized, Refinement, Differential and Innovation" Little giant enterprises in Jiangsu Province, Model
tests were also performed using residual estimation, And the patent number prediction model of
"Specialized ,Refinement, Differential and Innovation" Little giant enterprises in Jiangsu Province has been
successfully established.
1 INTRODUCTION
Specialized, Refinement, Differential and Innovation
"little giant" enterprises are the leaders among small
and medium-sized enterprises. They are focused on
market segmentation, strong innovation ability, high
market share, grasp the key core technologies,
excellent quality and efficiency of the vanguard
enterprises, with the characteristics of "specialization,
refinement, characteristics and novelty" (Lu, Gao,
2020; Dong, Li, 2021)
0
. By the end of 2021, the
Ministry of Industry and Information Technology had
cultivated 4,762 national Specialized, Refinement,
Differential and Innovation "little giants" enterprises.
This paper predicts the number of listed Little giant
enterprise patents by GM (1.1) model in Jiangsu
Province.
2 GM (1.1) MODEL
CONSTRUCTION
The basic idea of GM (1.1) model is that the original
sequence is generated once. Due to the accumulated
sequence has an exponential growth trend, the
approximate first-order differential equation is used
to establish the model, and finally the modeling
sequence is reduced to complete the prediction of the
development trend of the original sequence (Xiao,
He, 2021).
The original sequence is:
X(0) = {x(0)(1), x(0)(2), … , x(0)(n)}
X(0)Next, add up to generate as follows:
X
(
)
(K) = X
(0)(i),K=1,2,3, ··· n (1)
A sequence with exponential laws is generated as
follows:
X

={X

(n)}
Grasp X(1) The sequence is approximately the
solution of the first-order differential equations.
