How to realize the sustainable development of mariculture industry——Re-examine from the perspective of biased technological progress in China

Abstract

With the high-intensity development of China’s mariculture, the contradiction between the deterioration of ecological environment and the demand for production growth has intensified. How can Chinese mariculture overcome the above problems and achieve sustainable development? Theoretically, biased technological progress has a great deal in optimizing resource allocation, improving the efficiency of mariculture, promoting large-scale production and reducing pollution. Based on translog production function, this paper intends to combine the input-output characteristics of mariculture to make an accurate judgment on biased technological progress of China’s mariculture, investigates the matching problem between biased technological progress and factor endowment, so as to better play the important role of technological progress in promoting the sustainable development of mariculture. The results show that: the factor bias of technological progress in China’s mariculture is to use labor first, followed by mariculture area and capital. Both index BiasLK and BiasLS have a decreasing trend on the whole, indicating that the trend of technological progress towards labor use has slowed down. The factor market is interfered by the state administration, and the prices of some factors are distorted, which can not reflect the scarcity of factors. The factor bias of technological progress of mariculture in China’s coastal regions is basically the same as the national situation. There are differences in the value of the index among different provinces, while the differences in technological progress across factors are relatively stable. Finally, this paper puts forward the corresponding policy recommendations.
