Research On The Industrial Upgrade Of Heilongjiang Province’s Dairy Cattle Breeding Industry From The Perspective Of Manure Resource Utilization

Dairy farming is a basic industry in Heilongjiang Province and an industry whose economic contribution rate has remained stable for a long time.Although the overall development trend is stable,the development of dairy farming in various regions in the province is not balanced;combined with industrial policy orientation and modern development trends,dairy cows Pollution in the aquaculture industry is not only the main factor restricting the development of the industry,but also a turning point in promoting industrial upgrading;in order to improve the pollution status of dairy farming and solve the problem of equilibrium in the development of the dairy farming industry in the region,this article takes the microscopic perspective of the utilization of manure resources and integrates the development of the industry.The basic current situation and macro policy background of Heilongjiang Province will explore the specific path of industrial upgrading of dairy cattle breeding industry in Heilongjiang Province,with a view to accelerating the modernization,large-scale and rational development of dairy cattle breeding industry.This article first sorts out the basic situation of the dairy farming industry in Heilongjiang Province and calculates the industrial upgrade coefficient in combination with important factors related to industrial upgrading,and has a preliminary grasp of the changing trend of the dairy farming industry in various cities;secondly,it analyzes based on the theory of circular economy and the theory of endogenous growth.The industrial upgrade of dairy farming industry requires the utilization of manure resources,and combined with manure resource utilization mode,the resource utilization potential of dairy manure is divided into fertilizer substitution potential and energy substitution potential;at the same time,according to the amount of manure emissions and The recyclable quantity was measured,and it was found that although dairy cow farming pollutants are the main source of agricultural pollution,both the use of manure and fertilizer and the use of energy can exert its energy substitution potential and improve the current pollution situation.Based on the energy substitution potential of manure from dairy farming,the relevant panel data of13 cities in Heilongjiang Province from 2006 to 2019 were selected,and the two-way fixed effect model was used to compare and analyze the two resource utilization methods.The overall analysis results show that: manure The utilization of sewage resources has a significant promotion effect on the industrial upgrading of dairy cattle breeding industry,and the utilization of manure energy has a better effect on the promotion of industrial upgrading than the utilization of manure fertilizer.At the same time,the core explanatory variables and the annual dummy variables are interactively analyzed,and the regression results of the quantitative indicators of the two manure resource utilization modes and the industrial upgrading coefficients of various cities in the province are obtained.The results show that : in terms of applicability,manure fertilizer The model of chemical utilization is better than the model of energy utilization of manure.Due to differences in the inventory,infrastructure investment,and the area of ??arable land used to absorb manure in various cities,there are significant differences between the analysis results at the regional level and the overall analysis results;finally,the actual status of the factors related to industrial upgrading and the empirical analysis results are proposed Promote the utilization of manure resources,increase the attractiveness of industrial funds,take into account the differences in industrial scale,and realize the adaptation of manure resources utilization and industrial upgrading,etc.,to provide practitioners with technical guidance and improve the production system to obtain more economic benefits It is a practical method to improve the difficulties and shortcomings faced by the industrial upgrading of the dairy cattle breeding industry in Heilongjiang Province,and solve the problems of uneven regional development and insufficient utilization of resources.
