| Opening-up has been a basic state policy of China for a long time,and China has always adhered to a win-win strategy of opening-up to provide inexhaustible impetus for its own development and progress and the sound performance of the world economy.However,with the change of the international division of labor,the gradual formation of the global value chain and the acceleration of the flow of production factors,the domestic and foreign competition pressure is increasing.In the past,with cheap labor as the main advantage factor,China’s development mode of undertaking labor-intensive low value-added production links at the bottom of the "smile curve" is increasingly weakened in the current environment,and the demand for selling high value-added products,obtaining value chain optimization,and realizing the overall upgrade of product quality is increasing.In 2018,the Central Economic Work Conference proposed "institutional opening" for the first time in the new expression of opening up,its purpose is to promote all-round opening up.By adapting to the new situation and grasping the new characteristics,we will promote the transformation of opening-up based on the flow of goods and factors of production into one based on rules and other institutions.Therefore,in order to further promote the quality of Chinese export products and increase the competitiveness of Chinese export products,this paper based on previous studies,through the institutional opening and the quality measurement of export products,creatively using institutional opening as the entry point to study the effects of institutional opening on the quality of export products.Firstly,by analyzing the relevant studies of previous scholars,this paper sorts out the definition and measurement of institutional opening and export product quality,and summarizes the possible influencing factors mentioned in previous studies of scholars.The results show that the measurement of institutional opening by previous scholars is not perfect,and the influence path of institutional opening on the quality of export products is not clear.Therefore,based on Porter’s "diamond theory",the paper concludes that institutional openness may affect the changes in the quality of Chinese export products by optimizing allocation of production factors,stimulating domestic demand,intensifying domestic market competition,optimizing domestic industrial structure,restraining enterprise management risk,and actively improving system design through six kinds of ways,and puts forward four reasonable hypotheses.Then,in the measurement of institutional openness and export product quality,we find that the export product quality and institutional openness level of our country are rising positively,but the gap between coastal province and non-coastal province is great.Coastal province is obviously better than non-coastal province in both indicators,but non-coastal province has stronger development potential.In order to verify the reliability of the above theoretical hypothesis,the fixed effect model,the intermediary effect model and the threshold effect model are used for empirical test.The empirical results show that institutional openness can not only promote the upgrading of the quality of Chinese export products directly,but also affect the improvement of the quality of export products indirectly by affecting the consumption demand of local residents.However,from the intermediary effect of innovation efficiency,institutional openness has a significant negative impact on the innovation efficiency of the region,while the impact of innovation efficiency on the quality of export output shows an obvious U-shaped structure.From the threshold effect,the influence of institutional opening on the quality of export products will decrease with the upgrading of our industrial structure.The above empirical tests prove the rationality of the theoretical hypothesis in this paper and provide ideas for the subsequent research of scholars.In order to clarify the reasons for the differences between coastal provinces and non-coastal provinces in Chapter 4,this paper conducts a special heterogeneity test.The results show that the impact of institutional opening on the quality of export products in coastal provinces is significantly smaller than that in non-coastal provinces.From the perspective of the dimensional test of institutional opening,the business environment is an important index affecting the quality of Chinese export products.Finally,based on the above research,this article from the government and enterprise level respectively put forward corresponding countermeasures,hope to help our export products quality further improvement.From the government level,this paper puts forward the following suggestions:(1)The government should strive to create a good environment for foreign exchanges and continuously enhance the attractiveness of foreign exchanges.(2)Strengthen the deep integration of regional industrial structure and institutional opening up.(3)Pay attention to the influence potential of institutional opening in non-coastal areas on the quality of export products.From the enterprise level,this paper proposes:(1)to improve the importance of domestic demand.(2)Strengthen the independent innovation capability of enterprises. |
