The Dynamic Effects Of Environmental Pollution On Tumor Incidence

The economic development at the expense of environment has brought serious environmental and health problems. The reports about environmental pollution have frequently appeared in public view in recent years. Although environmental protection efforts have been greatly improved, the relevant laws and regulations are accordingly introduced, the concept of low-carbon economy has been putted up for many years, but it is undeniable that fog and haze becomes worse, and the environmental problems did not get substantial improvement. At the same time, cancer and cancer village maps also reveal the emergence of the high cancer incidence at the current situation.In order to study the relationship between environmental pollution and the incidence of cancer, to demonstrate the impact of environmental pollution on cancer incidence with data. This paper quantitatively measures the dynamic effects of environmental pollution and the regional characteristics of the provinces of tumor incidence by constructing a dynamic panel data model with interactions effects. And the method of system GMM estimation and iterative principal component analysis are used to estimate the model parameters. The results show the dynamic effects of the pollutants like industrial smoke-dust?sulfur dioxide and wastewater on tumor incidence are inverted U-shaped. It means that the effects gradually increase over time increases, decreases after reaching the maximum value. And these three pollutants have lag effects on tumor incidence, and the maximum effects all occur at the third year lag. Whether it is short-term, medium-term or long-term effects, the order of effects of each pollutant from small to large is: industrial sulfur dioxide, smoke-dust and wastewater. Tumor incidence of long-term elasticity of three pollutants are: 102.4218,88.1134,32.2587, meaning in the long term, industrial smoke dust, sulfur dioxide and wastewater emissions per capita grew by 1%, the incidence of cancer increases by 88.1134%, 102.4218%, 32.2587%. The tumor incidence determined by a common non-quantifiable social factor are rising gradually, and Guangxi, Hunan and Henan provinces are most sensitive to this trend. This may be related with the local diet or cultural, this conclusion also supports the view from China Cancer Registry Annual Report.Finally based on the increasingly serious environmental pollution and rising incidence of cancer facts, we propose to enhance environmental quality control and residents' health protection and other related work on institution construction and technology upgrading, and constantly optimize our industrial structure, enhance innovation capability, the phasing out of backward production capacity. But also to establish and improve environmental protection and health of residents comprehensive monitoring system, strengthen coordination of environmental pollution and the construction of an early warning mechanism between the various departments.
