    Jianfang Li, Jiachen Wang, Tongtong Sun , Shi Yin

    In the context of the widespread application of digital technologies such as the Internet, big data, artificial intelligence, and cloud computing, digital transformation in the manufacturing sector has become an important engine to promote high-quality economic development in Hebei Province. This paper aims to objectively analyze the current situation of industrial integration between the Beijing-Tianjin-Hebei digital economy and the manufacturing industry, and conduct level measurement, so as to promote the in-depth integration and development of the digital economy and manufacturing industry in Hebei Province, so that the manufacturing enterprises in Hebei Province can rebuild their competitive advantages in the future development, finally realize digital transformation, and promote the high-quality development of the manufacturing industry in Hebei Province. Therefore, it is very important to carry out empirical research on the integrated development of digital economy and manufacturing industry in Hebei Province. First of all, this paper constructs the index evaluation system of digital economy and manufacturing industry respectively, takes the relevant data of Beijing-Tianjin-Hebei region in recent five years as data samples, uses entropy weight-TOPSIS method to measure the level of digital economy development and manufacturing industry transformation, and uses the coupling coordination degree model to measure the level of industrial integration of the two.

    Time-varying effects of crude oil price fluctuations on tuna fish prices

    Pierre Failler, Yuhang Zheng, Yue Liu, Negar Akbari, Helga Josupeit, Andy Forse, Benjamin Drakeford

    This research presents an investigation of the time varying effects of crude oil on the price of three Tuna species, namely skipjack, albacore and yellow fin. The investigation analyses the impact coefficient of oil price fluctuation on tuna species over time with specific phases related to time points when crude oil prices fall, including December 2008 (due to the impact of the Financial Crisis), February 2016 (due to the impact of the US shale oil and gas revolution) and April 2020 (due to the impact of the global COVID-19). The analysis shows that the price of yellow fin and skipjack show sensitivity to these phased oil price shocks however stay consistent after recovery. This research finds that the relationship between oil price and Tuna price depend on specific phases of the oil price fluctuations and that global crude oil price shocks could have immediate and short-term impacts on fish markets especially during a period of financial crisis.
