The manufacturing industry is the skeleton of a country′s economy, which is the foundation of national wealth, technological innovation and national defense. The quality of manufacturing industries is the measurement of economic efficiency, production technique efficiency, structure balance, material and energy consumption ratio and pollution discharge etc.that is combination of economic efficiency, factor efficiency and social efficiency. By extracting the essence of quality of manufacturing industry, the paper has established manufacturing development quality indicators which is the main innovation points of the paper, to reflect the quality of factor allocation and environmental improvement degree, which includes industrial contribution ratio and environmental improvement degree that embodies manufacturing industry efficiency and sustainability. 

Ten hypotheses have been put forward through theoretic analysis of the effect of factor endowment such as human quality, research and development investment,state-owned and foreign capital proportion, and industrial environment such as industrial competition, supply-demand situation, industrial specialization, industrial tax policies, industrial export, import of technical parts, and macroeconomic environment such as financial development level and environmental regulation and investment etc. on the quality of manufacturing industries. 

By collecting data of physical investment and human capital of manufacturing enterprises in scale from 2000-2015，calculating manufacture development quality index and influencing variables such as R&D investment, human capital quality etc., the paper has used correlation analysis and econometric model to verify the validity of the hypothesis, which is exploring the effect of factor endowment and business environmental factors on manufacturing development quality, and seven hypothesis has been confirmed while a hypothesis is falsified and two hypothesis could not have been verified. 

Findings show that R&D investment, pollution abatement, human capital quality promotes the quality of manufacturing industries, which means that high-quality R&D investment and human capital may increase the efficiency of manufacturing industry and pollution abatement helps reduce pollutant discharge to protect environment. That state-owned capital and demand-supply situation have the strong positive effect on manufacturing development quality, which proves that state-owned capital may support long-term research & development investment and technological innovation, and workable competition situation between demand and supply may urge enterprises improve operations. The ratio of manufacturing export-import and foreign capital proportion, industry concentration degree and tax rate imposes negative impact on manufacturing development quality,which reveals that in the past period the manufacturing export-import and foreign capital lead manufacture industry relying heavily on technical parts and capital abroad, and that industry concentration degree upgrading and tax ratio rising reduce the industrial effective competition and discourage business initiatives. 

According to the analysis results above, policy suggestions are that advancing domestic R&D investment and human capital which is the most important active elements to promote technological innovation & progress and improve business performance, that strengthening the pillar position of state-owned capital in technological catching up and talent cultivation to conquer core technology autonomously because the characteristic of state-owned may guarantee the R&D willpower to overcome key core technology which needs large volume and long-term investment, that reducing dependence on foreign technology and key components & parts gradually by strengthening R&D, that improving the level of technology and added-value of manufacturing export products, and saving energy and reducing emission by increasing green technology R&D to upgrade manufacturing development quality on basis of the promotion of technology and efficiency.
