The China National Petroleum Pipeline Network Group Co., Ltd. was established on December 9, 2019, which marked the separation of large⁃scale oil and gas pipeline network from petroleum and petrochemical companies, followed by a new stage of independent operation of oil and gas pipeline network in China. As an important part of the oil and gas pipeline network, similar to the crude oil pipeline network and the natural gas pipeline network, the refined oil pipeline will experience a major change in its operating model after reorganization into the National Petroleum Pipeline Network Group Co., Ltd.This paper analyzes the differences between several typical operating modes of refined oil products pipeline, explains the shortcomings in the transformation and adaptability of refined oil pipelines in China. The reform methods of refined oil products pipeline are discussed, and the corresponding suggestions are put forward.

Under the background of Chinese culture, the influence of employee innovative behavior under the transformational leadership was studied, then the mediating role of psychological empowerment in the process of impact was explored.With the method of questionnaire, enterprise employees were taken as the research object from four cities Beijing， Tianjin， Shenyang and Dalian in the north area of China, and an empirical analysis was made of 381 valid questionnaire data. The results showed that transformational leadership was respectively positively related to psychological empowerment and employee innovative behavior; The psychological empowerment was positively related to employee innovative behavior; Meanwhile psychological empowerment partially mediation between transformational leadership and employee innovative behavior.

In order to research on the impact of imbibition effects, mechanisms and the correlation factors of the tight oil cores, the experimental devices of tight core imbibiton were established. The experiments of oil-water imbibition of tight sandstone were carried out. The effects of temperature, pressure and surfactant on the oil-water imbibition in compacted core were studied. The curves of imbibition efficiency versus time, characteristic points of curve and the influential factor of imbibition were analyzed. The imbibition law and characteristics of tight sandstone core were obtained. The results showed that the effect of imbibition was mainly occurred on the surface layer of the tight oil core. The temperature had a large effect on the second stage of imbibition. The oilwater imbibiton efficiency of the single tight oil core is about 10%, which is about 25% under the formation conditions.

The multiple linear regression model was established in the base of related theoty of executive compensation and corporate performance, calculating the comprehensive scores of corporate performance from PCA with the samples of listed companies in Jiangsu province, to research the relationship between the executive compensation and corporate performance. The political suggestions to improve the salary incentive mechanism and solve principal-agent problem were put forward.

With China's economic sustainable development, people's living standards improved, but the attendant environmental problems are increasingly prominent, the greenhouse effect is particularly prominent. Many scholars pay much attention to the relationship between China's carbon emissions and foreign direct investment and export trade. The effect of foreign direct investment and export trade on carbon emissions were studied through the panel data of 28 provincial units of 2000-2012. The results show that the total amount of foreign direct investment was a positive correlation with the carbon emissions in China. From the relative close degree, foreign direct investment on carbon emissions was greater than the total amount of export trade. 

With the development of our national economy, the scale of investment increased gradually at the business. The characteristics of the introduction of FDI scale of 19992013 in Liaoning province were summarized, to evaluate the carbon emissions from 1999 to 2013 in Liaoning province. Correlation between exploring the introduction of Liaoning province FDI scale and carbon emissions was studied, and the econometric methods was used. Through the ADF unit root test, cointegration test, the Grainger causality test, and generalized impulse response function method, the relationship between the identities of both was established, and a detailed analysis was made, the relevant reduction of Liaoning province carbon emission was put forward to propose according to the empirical conclusion.
