生态脆弱地区林业全要素生产率变动及其影响因素OA北大核心CSTPCD

[Objective]Against the backdrop of ecological civilization construction,changes and influencing factors of total factor productivity of forestry in underdeveloped and ecologically vulnerable areas were studied.The feasible paths to improve the total factor productivity of forestry were explored from the forestry resource investment and allocation,the production and operation scale adjustment and other perspectives.Thus,it provided scientific basis and theoretical support to accelerate in transforming forestry development mode and formulating the policies that contribute to the high-quality forestry development in homogeneous alpine collective forest area where ecological vulnerability and economic poverty overlap.[Method]A DEA-Malmquist model was established with fund,land and labor as input factors and economic,ecological and social benefits as output factors on the basis of the tracking investigation data of 500 peasant households in Gansu Province from 2009 to 2018.A panel Tobit model was constructed by selecting 13 variables out of 6 dimensions comprising householder characteristics,family characteristics,woodland characteristics,location characteristics,forestry policies and forestry services.Thus,the total factor productivity of forestry in Gansu Province was measured and calculated and its influencing factors were analyzed.[Result]1)From the perspective of holistic change,the growth in total factor productivity of forestry is insufficient,and the reason is that each component has not developed into synergy.Specifically,the growth in total factor productivity of forestry is driven by technology advancement while technological efficiency,pure technological efficiency and scale efficiency have presented only limited promotion effects.2)From the perspective of temporal characteristics,the total factor productivity of forestry is in an unstable state(presenting alternating up-and-down fluctuations from 2010 to 2018)and a sustainable development in forestry productivity remains unfulfilled.3)From the perspective of regional characteristics,the total factor productivity of forestry presents obvious region-based differences due to the differences in both natural and historical conditions,and economic and social advancement.By region,the growth in total factor productivity of forestry is insufficient in eastern Gansu,limited in southern Gansu and fast in middle Gansu.By county territory,there is a great difference among counties in southern Gansu,followed by middle Gansu and the least in eastern Gansu.4)From the perspective of influencing factors,the total factor productivity of forestry is subject to the following factors,including age,cadre number,migrant worker headcount,proportion of forestry income to total income,extent where forest road meets the need,geographical location,difficulty in lumbering index application,access to forestry subsidy,participation in forest insurance,the difficulty in forest right mortgage loan and participation in forest cooperative society.[Conclusion]1)High value should be put to the basic research on forestry theories,the constant transformation and application of scientific and technological achievements in forestry and the reliance on scientific and technological progress so as to ensure the sustainable development in forestry.2)The training measures of forestry should be strengthened,and the efficiency of forestry technology should be improved.Attention should be paid to the effect of forestry technology,and the development mode of forestry should be shifted.3)The financing supply for forestry should be increased,and the standardized forest land circulation should be guided.The socialized service system of forestry should be completed,and the scale efficiency of forestry should be promoted so as to realize its scale economy.4)Technological progress should be improved continuously,and technical efficiency should be boosted gradually.Sscale potential should be tapped fully so as to prompt all productivity component to form synergy;the production factors of forestry should be allocated rationally and effectively.5)Forestry development among various areas should allow for the particularity of their own forestry resource endowment and the necessity and difficulty in ecological security.The targeted support policies should be provided to develop forestry based on local conditions;regional exchange and cooperation should be enhanced to facilitate regional common development.
