Study Of The Effects Of Agricultural Structure Adjustment In China

The paper aims to study the problems in China's agricultural structural changes since 1978. The study contains two parts; one is the theoretical part, the other empirical part. Theoretically, based on the theories of industrial structural change, resource allocation, industrial structural correlation and economic growth, the paper expands on the mechanism and impacts of agricultural structural changes on economic growth, and establishes the frameworks for the efficacy of agricultural structural changes. Empirically, the paper analyzes the change differences in agricultural structures between China's and worldwide. That is, agricultural structures fall behind the industrial stages, agricultural sectors fall behind the overall economic development, and the structures of planting industries fall behind the market demand. Afterwards, the paper analyzes the impacts of agricultural structures on agricultural economic development. In this section, the paper analyzes the general efficacy of agricultural structural changes, establishes indices for evaluating efficacy, and expands on the contribution of agricultural structures on the agricultural economic development from producing sectors, input factors and demand structures respectively.The paper holds that under the macro environments, agricultural structural adjustments for China's agricultural development are necessary and imperative. At present, China's agriculture is changing from traditional agriculture to modern agriculture, and the changing process is characterized by low level of agricultural technologies, the laggard management mode, and peasants' low income, all of which can be improved through effective resource allocation. The main research results are shown as follows: (1) the problems in China's agricultural workforce: The agricultural workforce mainly rest on planting sectors, leading to a comparative low productivities in planting sectors, and ultimately low income level of peasants. (2) compared to other countries, China's agricultural structures differ. The differences mainly lie in that the planting sectors are overemphasized; the percentage of economic crops is relatively small, the percentage of stock raising sectors is small and irrationally-structured, the percentage of forestry and fishery industries are small, and produces manufacturing is fallen behind. (3) the increase in the input factors needed for the agricultural development. The workforce impacts agricultural economic growth through workforce productivity. China's agricultural growth is mainly dependent on the increase in workforce, but not on the efficiency increase in financial funds usage. From the analysis of all-factor productivity, China is now experiencing the problems caused by low high tech inputs, although it is changing from traditional to modern agriculture. (4) China's agriculture is not only influenced by the consumption demand and technology improvement, but also influenced to a great extent by the development of other industries.The innovations in the dissertation possibly lie in two aspects. (1) innovation in research perspective: The paper, centered on the efficacy, studies from structural perspective the correlation between China's agricultural structural adjustments and agricultural economic growth, trying to explain the impacts on agricultural structural changes on agricultural economic development. (2) innovation in methodologies: The paper adopts the analysis method of industrial structure, builds the frameworks for the analysis of agricultural structural efficacy as well as the indices for agricultural structural adjustments efficacy, and establishes the mathematical model for agricultural structural efficacy, and finally analyzes the efficacy of agricultural structural adjustments theoretically and empirically.
