Research On The Driving Mechanism For The Agricultural Productivity Growth Of Jilin Province

With the continuous development of Economy, productivity growth has become the most important base of economic growth. During Chinese economic growth, the contribution rate of total factors productivity has reached 30.89%, especially after openness reform, technology progress contribution rate has increased to 40.95% significantly and become the most important source of economic growth. As a big agricultural country, China's agricultural productivity growth is the the core of national wealth and the foundation of economic and social stability. However, from 1978 to 2007, China's agricultural total factor productivity annual growth rate is only 0.7% and the contribution for agricultural output growth is about 11.3%. The fact shows that in the 30 years since reform and opening up, the growth of China's agriculture is mainly depend on increase of resource input, rather than on total factor productivity growth, which is still very extensive. Therefore, during the economic transformation of China, we have to face the historic mission to change extensive agricultural growth to intensive agricultural growth, which make us study the problems of agricultural productivity growth. It will be very important for developing modern agriculture and building new socialist countryside. As China's major grain producing areas and the agricultural province, Agricultural growth of Jilin has become increasingly dependent on technological progress significantly. During the period from 1986 to 2007, the technological progress contribution rate of Jilin Province was 41.92%. However, it should be noted that due to the small scale of agricultural self-management, low management level, poor production conditions, the problems on insufficient capacity for sustainable development and difficulty of farmers income increase are still very prominent. In this case, the promotion of Jilin Agricultural productivity growth is a method to accelerate social and economic development in rural areas and to change the backwardness of agriculture in Jilin. Therefore, this paper build a theoretical model about agricultural productivity growth based on the classical endogenous growth theory, use Malmquist-Benchmarking model to measure and analyze the agriculture productivity growth for the measurement and analysis; give some empirical analysis about the driving mechanism of R & D investment, human capital investment and institution on the growth of agriculture productivity based on VECM model and Tobit model. Moreover, we proposed some countermeasures for the promotion of agricultural productivity growth. Specifically, this paper mainly include:1.Theory framework of agricultural productivity growthIn the basis of In-depth study about endogenous growth theory, this paper constructed a theoretical model of agricultural productivity growth, and try to show that agricultural productivity growth is driven by R&D investment, human capital and institutional change directly. The theoretical model is the footstone of the following empirical study and provides the theoretical framework to identify R&D investment, human capital, institutional change as the most important driving factors for agricultural productivity growth .2.Measurement and analysis about Jilin agricultural productivityBased on the theoretical study, this study uses nonparametric Malmquist indexes to measure agricultural productivity of Jilin, not only try to show the predominant nature of Malmquist-Benchmarking model through comparing three different Malmquist indexes models; but also give a analysis about the agricultural productivity, agricultural technical efficiency change and agricultural technical changes according to the information reflected by results3.Analysis on the driving mechanism of R&D investment on agricultural productivity growth,In the framework of Western economic theory, capital is the basic element of economic growth. From the actual situation of Jilin's agricultural development, we can find the main driving power of R&D investment may include self-invested R&D investment, the R&D spillovers of leading enterprises, R&D investment from the other regions. For these three forms of investment, this study uses VEC models to make a quantitative analysis on the influence of R&D investment on agricultural productivity, which reveals the driven mechanism of R&D investment over the agriculture productivity growth.4.Analysis on the driven mechanism of human capital on agricultural productivity growthLabor is the essential element for Agricultural productivity growth, especially in the endogenous economic growth theory framework, the concept of human capital has been introduced into economic growth model, which gives the factors of labor new and more complex connotations. Lucas pointed out that human capital not only has the internal effect on productivity, but also has some external effects that makes human capital become the "economic growth engine." Now days, human capital factors that influence agricultural productivity growth include the quality and number of agricultural R&D personnel, the average education level of farmer, the situation of farmer's health. In view of this, this study used VEC models to make a quantitative analysis about the impact of human capital accumulation on agricultural productivity, which not only reveals the role of labor for agricultural productivity, but also clarifies the"learning-by-doing"or "technology diffusion" in the process of productivity growth.5. Analysis on the driven mechanism of institution on agricultural productivity growthInstitution has been less involved in the research, which is undoubtedly an important factor affecting agricultural productivity. As complexity of institutional variables and data availability, this study discussed the leading effects, incentive effects and the possible inhibitory effect in theory. Moreover, we defined the main institutional factors as agricultural fiscal support, financial support, agricultural price support policy, agricultural land policy and the promotion policy of modern agricultural, and analyses the influence of institutional factors on agriculture productivity with Tobit models.6. Coupling countermeasures on promoting agricultural productivity growth of JilinBased on the empirical analysis, this paper proposed some coupling countermeasures on promoting agricultural productivity growth of Jilin as following: (1)we should correctly grasp the trends of agricultural productivity and persist the strategy of promoting agricultural modernization; (2)optimize agricultural R&D investment and start agricultural technology innovation; (3)strengthen the dominant position of the leading enterprises for innovation and build university-industry platform; (4)focus on agricultural science and technology personnel training and start the agricultural science and technology human resources strategy; (5)raise the intellectual capital level of farmers and accelerate health capital accumulation; (6)increase agriculture fiscal, financial support and encourage agricultural development in key areas; (7)protect agricultural chain and create new land transfer mechanism. Among them, There are some innovative thinking such as establishing special incentive fund for leading enterprise technology innovation and encourage high-quality planting industry etc.
