Agricultural Technology And Carbon Emissions Correlation Studies In China

Under the momentum of rapid economic development, the rapid increasing in carbon emissions has become our country and even around the world’s challenging problem in the process of economic development. Carbon emissions caused by climate change has already gradually appeared, it becomes the focus of the scientific researchers attention from national political, economic, social, science and all walks of life. Taking measures to control emissions had reached a consensus between the countries all over the world. As a big developing country, China also make their efforts to governance and control carbon emissions. In 2009, our country put forward a goal of "Greenhouse gas emissions to the unit of gross domestic product in 2005 decreased by 40%-45% till2020." What’s more, in 2014 put forward another goal of “Greenhouse gas emissions to the unit of gross domestic product in 2005 decreased by 60%-65% till2030.”Agricultural greenhouse gas emissions accounted for about 10.97% of the total emissions, is the second largest contribution to greenhouse gas emissions after energy consumption. Farmland emissions accounted for 40% of the total agricultural carbon emissions, is also one of the main source of agricultural carbon pollution. So, exploring the measures of agricultural carbon emission reduction of our overall greenhouse gas emissions is of great significance, at the same time, having enormous potential to reduce emissions. Therefore, the author tend to explore and promote agricultural carbon reduction measures and policy system basing on the analysis of the status of China’s carbon emissions, on exploring the relationship between agricultural technology and the carbon emissions and on the experience of developed countries.In order to solve the problems above, the author Use an environmental economics related theory, econometrics and by using econometric model to carry on the research.First of all, the paper analyzes our country agricultural technology and agricultural development situation of carbon emissions from the perspective theory; then, using the principal component analysis(pca) to build the evaluation index system of agricultural technology in our country, at the same time, calculating the carbon emissions from different carbon source of agricultural. Finally, this paper discusses the relationship between agricultural technology and agricultural carbon emission, and proving basis for the current and future agricultural carbon reduction policy. The results of the study areas follows, currently, Agricultural technology development in our country is seriously depending on mechanization production mode. 30 provinces’ agricultural carbon emissions in our country is on the rise, among them, CO2 emissions which cause the use of growth of agricultural production is relatively stable, while, carbon emissions from rice and upland crops fluctuate within a short period of time, but the overall trend has not changed. Through analysis, there is a cointegration relationship between Agricultural technical index of comprehensive score of each carbon source and greenhouse gas emissions. The development of Agricultural technology is the granger reason of CO2 emissions increase by using means of agricultural production, the development of Agricultural technology is the granger causes of CH4 emissions from rice planting and the development of Agricultural technology and upland crops produce N2 O emissions are not the granger reason of the other party. Based on the empirical study results above, this paper introduces and summarizes the advanced low carbon agricultural experience in developed counties, combining the actual national conditions,putting forward more targeted and rational policy recommendations to our country agricultural technology and agricultural carbon emissions.
