4. Discussion
The above empirical results give us the following implications. First, there still is great space for manufacturing servitization in Zhejiang Province. Our empirical analysis suggests that the service quantity's erosion to per capita profit only starts to diminish when service quantity exceeds 2 and the positive contribution of service quantity to per capita profit begins to show when service quantity is further increased to around 4. Currently, the average service quantity of manufacturing firms in Zhejiang is 2.1, indicating great room for the development of manufacturing servitization. Continuous endeavor is still indispensible in order to reap the rewards of servitization.
