Introduction
At present, the research on high-quality development and the power source of high-quality development are basically focused on the macro level, mainly including the economic analysis of high-quality development ( So (1) what is the current level of high-quality development of equipment manufacturing industry in Liaoning Province? (2) What are the characteristics and conditions of high-quality development power transformation of Liaoning equipment manufacturing industry in the new era? (3) In order to realize the highquality development of equipment manufacturing industry in Liaoning Province, in what aspects should the government give policy support? We explore and analyze these problems theoretically and empirically.

The scale of equipment manufacturing industry in Liaoning Province
(1) In recent years, the scale of total industrial output value, the development of equipment manufacturing industry in Liaoning Province has entered a bottleneck period, and the total industrial output value shows a significant downward trend. (2) The investment scale of fixed assets and the scale of total output value show the same trend. In 2015, there was a sharp decline; in 2017, it remained low, but the drop was 5.05%. (3) From 2012 to 2017, the number of enterprises showed a downward trend year by year.

The structure of equipment manufacturing industry in Liaoning Province
Equipment manufacturing industry in Liaoning Province mainly includes metal products industry, general equipment industry, special equipment industry, automobile industry, railway, ship, aerospace and other transportation equipment industry, electrical machinery and equipment industry, computer, communication and other electronic equipment industry, and instrument and meter industry. According to the standard of total industrial output value, automobile manufacturing industry, railway, ship, aerospace and other transportation equipment manufacturing industry account for half of the equipment manufacturing industry in Liaoning Province.

Construction of evaluation index system for high quality development level of equipment manufacturing industry
The evaluation indexes of high-quality development evaluation system of equipment manufacturing industry include five dimensions: industrial innovation development, industrial coordination development, industrial green development, industrial opening development and industrial sharing development. The coordinated development of industry is mainly measured by the volatility of output value. The green development of industry mainly includes the measurement index of total energy consumption. The development of industrial development is measured by the proportion of product exports in total output value. Industrial sharing development selects the proportion of equipment manufacturing employees in total employees as the measurement index.

Evaluation of high quality development level of equipment manufacturing industry
After the introduction of education dividend, although the population of the three Northeastern provinces decreased, the population quality may be improved to a certain extent, and have a certain impact on economic growth. Education bonus to improve labour quality. Education dividend improves human capital stock. Education dividend to improve the level of science and education innovation.

Evaluation method:
According to the actual needs, entropy weight method is selected to evaluate the high-quality development level of equipment manufacturing industry in Liaoning Province. The basic principle of entropy weight method is to determine the objective weight according to the variation of index. Generally speaking, the smaller the information entropy of index in comprehensive evaluation is, the greater the variation degree of index, the more information it can provide, the greater the role it can play, and the greater the weight it occupies in the evaluation system. On the contrary, the larger information entropy the index has, the less variability the index has, the less information it provides, the less role it plays in the comprehensive evaluation, and the less weight it occupies.

Evaluation results:
The data used in this paper are mainly from Liaoning statistical yearbook, China Science and technology statistical yearbook and China Industrial statistical yearbook, which are compiled by the National Bureau of statistics. Entropy weight method is used to evaluate the high-quality development level of equipment manufacturing industry. It is not difficult to find that the starting point of high-quality development level of equipment manufacturing industry in Liaoning Province is relatively high, and there is a good trend of high-quality development between 2007 and 2014.
4 Analysis on the power source and change trend of high quality development of equipment manufacturing industry in Liaoning Province in the new era

Overview of power sources
At present, there is no detailed academic definition of the power for high-quality development of equipment manufacturing industry. This paper analyzes the power source from two aspects of supply and demand by referring to the power classification method of Sun Yue and Shi Haoting (2018). In some periods, the power is concentrated on the demand side; in some periods, the development power is more inclined to the supply side, but in the new era, the supply side power has gradually shown the pulling effect on the high-quality development of the equipment manufacturing industry.

variable selection and data description:
Based on the above theoretical analysis, the main explanatory variables are selected in this paper, as shown in Table 1

model construction:
This paper summarizes the above dynamic sources, taking the comprehensive score of high-quality development level of equipment manufacturing industry as the explanatory variable, which is divided into two models: demand (formula 1) and supply (formula 2), respectively explaining the contribution of each power source to the high-quality development of equipment manufacturing industry. The model is.
This paper adopts the form of double logarithm model:

Empirical results:
The results of ADF unit root test show that the comprehensive score of high-quality development level of equipment manufacturing industry, four investment, export, capital input, labor input and innovation input indicators are single and integral in the second order, all of which can pass the stability test.The weighted least square method can effectively eliminate the heteroscedasticity. Therefore, the weighted least square method is used for regression estimation in this paper. From the results of model (1) and model (2), it can be seen that the export pull on the demand side is slightly weak, and the investment pull is greater; among the power sources on the supply side, the labor input plays the largest role, which is higher than the capital input and technology input. In co integration analysis, R1 is used to represent the residual in demand model and R2 is used to represent the residual in supply model. Because the residual items pass the ADF test, there is a long-term cointegration relationship between independent variables and dependent variables.

Trend analysis of dynamic change
From the results of model (3) and model (4), it can be seen that the driving force on the demand side of the province with strong equipment manufacturing industry is also weak, and the driving force on the export side is slightly larger; among the power sources on the supply side, the driving force of labor input is negative, indicating that in the province with strong equipment manufacturing industry, more labor input has no positive effect on the high-quality development of equipment manufacturing industry, and capital investment Both input and technology investment play a positive role, and at present, capital investment is more important. Therefore, in the future, the trend of high-quality development of equipment manufacturing industry in Liaoning Province is: (1) from demand side drive to supply side drive; (2) from factor driven to innovation driven 5 The policy choice of the dynamic change of the high quality development of equipment manufacturing industry in Liaoning Province in the new era
