Studies On The Economies Of Scale In Terms Of Forestry-paper Integration Project

It has a very important role to study on the economies of scale in terms of forestry-paper integration project, for the deal with the coordination between the forestry industry within the subdivision, forestry and agriculture, forestry and pulp-paper industry, the development of forestry-paper integration project with a good balance between transportation and other industries, the relationship between promotion and constraints in forestry-paper integration project planning and construction to determine appropriate scale and reduce the waste of social resources to enhance the project's economic, ecological and social benefits.In this paper, it has been based on the basic principles of forest management and sustainable forest management planning and resource management, the basis of existing theoretical results and practical experience about forestry-paper integration and economies of scale, and the integrated use of theory induction, qualitative analysis, quantitative analysis, MFA and the CSA model creation, empirical analysis and other methods, combined with practical case of economies of scale on the forestry-paper integration project to undertake research.The paper is divided into seven parts. Firstly, the research background, purpose and significance, and research ideas, methods and structures were described.The second part is theoretical research, mainly on theory about forestry-paper integration and economies of scale. The evolution of guidelines on the paper industry's raw material, the connotation of forestry-paper integration and the results of domestic and foreign scholars' research are analyzed. The meaning, function, new features, theoretical foundations and the formation mechanism of economies of scale and the progress of the domestic and international research on economies of scale are discussed. The major theoretical achievements on economies of scale are summarized. At this chapter, the evaluation of theoretical research results has been made.The comparative analysis of forestry-paper integration situation between domestic and foreign are carry out at the chapter three. In this chapter, the main role and the characteristics of paper industry, the advantages of forestry-paper integration and the situation of forestry-paper integration between international and domestic are analyzed. The difficult problems of the implementation of forestry-paper integration and the existence error of economies of scale in the project are pointed out.In the fourth part, MFA (Multi-factors analysis) and CSA (Cost structure analysis) are used to study the factors of economies of scale in terms of forestry-paper integration project, the qualitative or quantitative relationship between these various factors. The main factors of forestry-paper integration project and the specific constraints and promote ways and means of these factors on the forestry-paper integration project are analyzed in-depth. Wood raw material pricing model and its impact on economies of scale of the project is researched and analyzed. The measurement model about appropriate scale of forestry-paper integration project was established. The analysis and demonstration in economies of scale of forestry-paper integration project were carried out relative clearly.The average cost is expressed by ACP. ACP=[(C1+C2+C3+C4)/Qw+Lpi*(β1+α1Q)]* (1+θ)*4+Lp2*(β2+α2Q)+Ω+0.7*[Pe+Lp3*(β3+α3Q)]+0.4*[Pc+Lp4*(β4+α4Q)]+λQγ+φ, whereλ>0,γ<0 (4-27)ACp'=Lp1*α1*(1+θ)*4+Lp2*α2+0.7*Lp3*α3+0.4*Lp4*α4+λγQγ-1 (4-28)ACp"=λγ(γ-1)Qγ-2>0(4-29)The scale of production with the lowest average cost is expressed by Q*.Q*=[-(Lp1*α1* (1+θ)*4+Lp2*α2+0.7*Lp3*α3+0.4*Lp4*α4)/(λγ)]1/(γ-1). This is a monotonically decreasing power function, when the rate of major goods transport costs Lp1,Lp2,Lp3,Lp4 rise, the lowest cost production value of forestry-paper integration project becomes smaller.Project profit is expressed byπ.π=P*Q-[(C1+C2+C3+C4)/Qw+Lp1*(β1+α1Q)]*4*Q-Lp2*(β2+α2Q*Q-Ω*Q-0.7*[Pe+Lp3*(β3+α3Q)]*Q-0.4*[Pc+Lp4*(β4+α4Q)]*Q-ρQμ-φ>*Q, wherep>0,μ>1 (4-35)π'=P-4*(C1+C2+C3+C4)/Qw-4*Lp1*β1-8*α1Q-Lp2*β2-2*Lp2*α2*Q-Ω-0.7*(Pe+ Lp3*β3)-2*0.7*Lp3*α3Q-0.4*(Pc+Lp4*β4)-2*0.4*Lp4*α4Q-ρQμ-1-φ(4-36)π"=-8*α1-2* Lp2*α2-2*0.7* Lp3*α3-2*0.4*Lp4*α4-ρμ(μ-1)Qμ-2<0, there is the maximum total profits of forestry-paper integration project.PartⅤis the case studies. Through the empirical analysis of economies of scale about bamboo pulp-paper integration project in Sichuan Luzhou, the econometric model of project scale is verified and the results of this study guiding the actual work is confirmed.In partⅥ, the strategy and measures to accelerate the realization of economies of scale of forestry-paper integration project were studied and the eight proposals to achieve economies of scale features of forestry-paper integration project were put forward.PartⅦis the conclusion, the whole thesis is summarized and the main innovation is pointed out. The application proposal of this research is presented. The future direction of Study and research is forecasted.
