A Study On The Impact Of Agricultural R&D Grant On Agricultural Total Factor Productivity In China

Agriculture is the foundation of the national economy.In the context of the increasing emphasis on the dual constraints of resources and environment in China's agriculture,the long-term growth of agriculture can not rely on the infinite input of factors of production and can only be achieved by increasing agricultural productivity.The improvement of agricultural productivity is the fundamental way to realize the agricultural growth and realize the modernization of agriculture in the future.Schultz believes that the key to the transformation of traditional agriculture is the introduction of new elements,to break the traditional agricultural balance,to achieve a qualitative leap in agricultural productivity.Romer,the new growth theory representative,stressed that technological change is at the center of economic growth,technological innovation is the result of research and development activities,can explain the vast majority of per capita output increase.The essence of agricultural modernization is to realize the leaping development of agricultural production efficiency through modern agricultural science and technology innovation and technological progress.Agricultural science and technology investment is to promote agricultural science and technology innovation,promote agricultural scientific and technological progress of the key factors,but also agricultural science and technology innovation and progress of the material basis and premise.There is no strong and efficient capital investment and improve the scientific and technological support system,agricultural productivity revolution and modernization of the transition is difficult to achieve.The Chinese government has always attached great importance to the agricultural research factors,and has introduced a series of programmatic documents to construct an effective agricultural science and technology system as a major strategic task.However,the current investment in agricultural science and technology in China,there are still a series of problems,such as low scale of investment in agricultural science and technology,inreasonable allocation and distribution of scientific and technological elements,not smooth enough of investment mechanism,no efficiency in agricultural science and technology investment and so on.What is the reason behind the deep-seated causes of these problems? How to move the China's investment in agricultural science and technology in the future? How should the flow of agricultural science and technology resources be planned and guided? The answer to the question depends on the role of agricultural science and technology investment in the process of agricultural development in China,whether it is effective in increasing productivity and how it works for productivity? In view of this,this paper attempts to establish a more comprehensive theoretical analysis framework,from the theoretical,practical and empirical three aspects of all-round in-depth discussion of China's agricultural science and technology investment on the role of agricultural production efficiency.The results and achievements of this paper can provide scientific basis for the inspection and evaluation of the driving effect of agricultural science and technology in China in the past two decades.On the other hand,it is also beneficial to the government to formulate and optimize agricultural science and technology policies and systems and tap the potential of science and technology resources.To provide a policy reference for improving the performance of agriculture,agriculture and agriculture.This paper generally follows the basic mechanism of agricultural science and technology why can affect the total factor productivity of agriculture,how to influence,and how to optimize the basic factors such as the effect of agricultural science and technology on agriculture's total factor productivity,the effect,the effect and the characteristic of agriculture The problem is discussed.Firstly,it analyzes the theoretical basis and principle of productivity impact of agricultural science and technology investment in China,constructs the theoretical framework of agricultural science and technology productivity effect,and systematically investigates the current situation of agricultural science and technology input and agricultural total factor productivity.And then from the practice,analyze and explain how the investment in agricultural science and technology into the hands of farmers,into the actual productivity of the mechanism.Then,on the basis of theoretical and practical analysis,we use a variety of modern econometric methods to carry out comprehensive and in-depth empirical tests on the productivity effects of agricultural science and technology investment from multiple dimensions,and quantify,contrast and explain different conditions through influencing factors Differences and Causes of Agricultural Science and Technology.Finally,according to the results of theoretical and empirical analysis,the author puts forward the ways to optimize the government science and technology and the relevant policy suggestions.The main conclusions of this paper are as follows:(1)agricultural technology plays an important role in the growth of total factor productivity in agriculture.However,due to the weakness of agriculture and the government China features a strong preference for the pursuit of economic growth,science and technology resources are "off conversion" and "non agriculture" trend,agricultural science and technology investment strength of our country is low for a long time.The future must further strengthen the agricultural science and technology attention,in ensuring the government investment based on the total increase,through the expansion of agricultural science and technology funding sources,optimizing investment structure,promote the efficiency of the use of funds and other ways to improve the agricultural science and technology investment accounted for the proportion of agricultural added value,the establishment of long-term mechanism of the steady growth of investment;(2)the current agriculture China's science and technology system and system defects,play a serious restriction role developing agriculture through science and technology.The central government should rationalize through strengthening the coordination ability,standardize the technology investment management mode,agricultural science and technology investment operation mechanism,rectify the default behavior,strengthen intellectual property protection and other measures,and gradually solve and improve the agricultural science and technology investment system;(3)agriculture science and technology contribution is mainly reflected in the promotion of technological progress,the effect of technical efficiency is not significant,but there are obvious stage characteristics and regional differences,there is still much room for improvement.Therefore,the regional science and technology resource configuration is not reasonable is the short board of agriculture science and technology at present,from two aspects: one is to optimize and improve the rational allocation of central and local resources of science and technology.Rationally construct the eastern,central and western regions of the distribution pattern,narrow the regional gap,mining science and technology "catch up effect";(4)research and development of agricultural science and technology achievement transformation and popularization,is the key technology for the transformation of productivity.We should continue to maintain the pluralistic mode of agricultural science and technology transmission in china.On the one hand,we should continue to improve the repair of the current extension system of agricultural science and technology,so that it can play a more effective role,on the other hand,active exploration and innovation,and gradually formed by enterprises,joint research and innovation mechanism of the integration of production,promotion of science and technology;(5)the productivity effect is heavily dependent on external conditions and environment variable should be mutual coupling and mutual matching relationship between elements,focusing on science and technology and other external conditions and factors affecting the weaknesses,and create a favorable external environment for science and technology play to maximize productivity effect,ensure agriculture science and technology,promote productivity growth effect;(6)industrialization,promote the city,and not to agricultural science and technology play a role to play a supporting role in the development of effective,but there is in the process of development of resources of agriculture "squeeze Accounting,and even become a major factor,resulting in inhibition of agriculture by science and technology science and technology productivity paradox.Measures should be taken to gradually break the unequal system of urban and rural areas in China,explore and innovate the coordinated development of workers and peasants,and combine the new industrialization with the urban and rural integration and the new urbanization.Compared with the existing literature,the possible innovations of this paper are as follows:(1)Research content: Compared with the industrial field,the current research on the impact of agricultural science and technology investment on productivity is relatively small,and more emphasis on empirical,theoretical Mechanism analysis,this paper attempts to establish a complete analysis of the three dimensions of theory,practice and empirical analysis of the framework,from the agricultural science and technology for the mechanism of the mechanism of action,the role of action and the role of the role and characteristics of several aspects,multi-(2)the method of research: one for the calculation of agricultural total factor productivity does not form a unified method,this paper intends to make a comprehensive analysis of the agricultural production efficiency of agricultural science and technology,compared with the previous research content is more systematic and complete;The three-stage DEA method is used to adjust the input variables,and the Malmquist index is used to estimate the change of total factor productivity of agriculture in 31 provinces and regions in China.It provides a useful attempt to quantify the total factor productivity of agriculture in China.The second is to establish the panel model Agricultural science and technology to promote productivity to improve performance,the use of tools The method of variable method can test and deal with the endogenous problem that may exist in the model,which is more reasonable than the previous one.The third part is the empirical test of the influencing factors,and the method of threshold regression can be used to describe more(3)the perspective of the research perspective: First,based on the different regions(in the case of different regions),the impact of the different thresholds on the dynamics of agricultural agglomeration,the impact of the variables on the quantification of more scientific and accurate,but also for the development of relevant policies to provide a more credible reference;,The different periods and the different productivity categories to estimate and test the difference between the impact of agricultural technology on productivity,and explore the causes of differences;Secondly,based on demand,supply and economic,policy,environment and other five levels of a more comprehensive and systematic inquiry The main factors affecting the productivity of agricultural science and technology,and its empirical test,the research perspective is more systematic than the previous literature.(4)the conclusion of the study: the current domestic most of the literature derived from the positive conclusions of the relevant conclusions,I do not fully agree.In recent years,the intensity of agricultural science and technology investment has increased year by year,but the growth rate of total factor productivity of agriculture in China has been decreasing.Based on the empirical test results,this paper finds out the possible "productivity paradox" phenomenon in the field of science and technology agriculture,analyzes and explains the technological input As well as the reasons for the formation of a certain degree of revision and expansion of the existing homogenization of the conclusion.All of these will provide new explanation and evidence for the complex relationship between agricultural science and agricultural productivity.It will also provide new ideas and enlightenment for the development and reform of agricultural science and technology policy and the improvement of agricultural productivity Innovation.
