The oil and gas industry plays an important role in the national economy. Among the many factors affecting the development of the upstream oil and gas industry, the role of technological progress is critical. Based on the theory of technological progress and economic growth, this paper used the data envelopment analysis (DEA) method to quantitatively calculate the changes of three indicators from 2003 to 2017 in 15 oil and gas producing provinces in China These indicators are technical effective value, total factor productivity and contribution rate of technological progress, to explain the specific effects of technological progress on the development of China’s upstream oil and gas industry. The results show that the technical effective values of different provinces vary greatly. Guandong, Sichuan and Qinghai are relatively high, while Gansu, Jilin and Henan are relatively low, and the important reason for the difference lies in the oil and gas resources and technical level. The total factor productivity of China's oil and gas exploration and development industry shows an overall growth trend, with an average
growth rate of 9.1% from 2003 to 2017, and its overall contribution to output during the same period was 215%, indicating that comprehensive technological progress had indeed made a significant positive contribution to the upstream oil and gas output. Furthermore, the analysis of total factor productivity shows that the average growth rate of technological progress, technological efficiency, scale efficiency and pure technical efficiency are 6.4%, 14.9%, 8.8% and 3.5% respectively, which indicates that technical efficiency improvement caused by the significant increase of scale efficiency is the main reason for the growth of total factor productivity. Against the background of increasing difficulty in prospecting for oil and gas resources, decreasing resource abundance, and reducing resource quality, China's oil and gas industry upstream exploration and development will be more dependent on the continuous progress of science and technology. This needs the government, the industry and related enterprises to work together. On the one hand, to pay attention to the impact of scale efficiency on the technical efficiency, and try to enlarge the scale efficiency through promoting the use of technology to finally improve the technical efficiency. On the other hand,
the investment in revolutionary technologies should be increased to solve various problems in the oil and gas exploration and development industry with emerging technological achievements, so as to promote the sustainable development of the oil and gas exploration and development industry.
